A week ago, the new Audi Q7 went on sale. This is the mid-term change of the second generation Q7. It is said that the appearance and interior have changed greatly. However, whether the reform is successful or not is not easy to judge at present, but also depends on market performance. After all, the market and time are the touchstones to test the quality of models. Just like the hot sale of the first generation Q7 and the silence of the second generation Q7, the sales volume is judged.
The first generation Q7 reached its peak when it debuted. It not only includes all the highlights of a medium and large SUV, but also carries the 12 cylinder version, which surprised many people just after it was listed, and it can quickly occupy the market and start selling well. By 20 15, the second generation Q7 was born, giving people a more heroic visual effect, or a little stingy, and the inner sense of luxury did not improve. The appearance failure also contributed to the sales of the second generation Q7, which not only failed to catch up with BMW X5 and Mercedes-Benz GLE for a long time, but was even surpassed by Volvo XC90 in 20 19. Fans generally believe that the first generation Q7 is the real Q7.
This test is also a story about not liking new cars. Customers are also very concerned about Q7 cars. After weighing their own budget and actual demand, they firmly chose the domineering old Q7. Customers are optimistic about a used car source in Zhengzhou. Let's take a look at the car!

According to the process, the inspection starts from the external paint surface and measures the thickness of a circle of paint surface. It is found that the cover, left front door, left rear fender and right front door have all been repaired with sheet metal, indicating that these parts have been bumped; Secondary painting of front and rear bumpers and right front fender; No cutting or welding was found. For a six-year-old used car, 1.2 million kilometers, the appearance maintenance is ok.
The paint value of the left front fender is lower than the average level of the whole vehicle. After checking the fender fixing screws, it is judged that the left front fender has been replaced. Fender belongs to the cover plate, and independent replacement will not affect the driving safety of the vehicle.
There is a crack in the front windshield, and there is no trace of accident collision repair around the windshield, so this crack may be caused by falling objects or stones. There is nothing wrong with the appearance. Next, check the engine compartment.
Open the front cover, the engine room is simply cleaned, and the old and new colors of the parts are clear at a glance; The engine occupies a lot of space in the engine room. It is a V6 3.0T supercharged engine with maximum power of 200KW, maximum horsepower of 272Ps and maximum torque of 400 Nm. Matching 8-speed AT automatic manual transmission and full-time four-wheel drive with Torsten differential.
There are traces of tightening and removing the fixing screws of the cover. Just now, we detected a small piece of metal on the surface of the cover. It is reasonable to remove the cover and repair the metal sheet.
There is no trace of unscrewing the right front fender screw, and there is no trace of sheet metal plastic repair on the inner crossbeam. The surface is naturally smooth and the paint surface is flawless. The left front fender was replaced, and there was a collision in the left front of the vehicle.
The production date of the right front headlight is 2065438+September 7, 2003, which is in line with the vehicle factory date range and has not been disassembled and repaired, so it is judged as the original headlight.
The production date of the radiator fan of the water tank is also within the factory date of the vehicle, indicating that it has not been replaced.
Observing around the water tank, it is found that the fixing screw of the water tank frame has been removed and replaced; Due to the small space in the engine room, it is temporarily impossible to see whether the front longitudinal beam is deformed due to collision. However, I have developed the occupational disease that I must see the longitudinal beam clearly. What I haven't seen will always stay in my mind, and I will definitely look for opportunities when I look at the chassis in the future.
The supercharged part of the engine intake pipe has been disassembled. After all, after running1.20 thousand kilometers, the disassembly and maintenance of the external parts of the engine is inevitable.
The valve cover fixing screw has not been removed, but there is slight oil leakage, which will make the engine oil smoke smell worse after a long time. It is recommended to remove the bonnet seal later.
There is no aging crack on the surface and inside of the generator belt, no abnormal sound when the tensioner hits the car, no leakage of the water pump wheel, no disintegration of the timing shell and no obvious oil stain on the surface.
There is no trace of disassembly and tightening of the engine crankshaft wheel fixing screw; Based on the above points, the suspicion of engine decomposition overhaul is ruled out.
There is nothing wrong with the main part. Let's take a look at the oil and water of the whole car. Oil dirt is worn out, so it is recommended to replace it; Brake oil and antifreeze can continue to be used; Good battery life.
After opening the door, the naked eye can hardly see any obvious wear and tear, and the car is clean and tidy. However, you can't just look at the surface. Many friends who buy cars, especially female buyers, book cars immediately because of their good interior and exterior colors. In fact, this is unprofessional, and careless soaking in water will not be reflected from these places at all. Let me see the details with a steel head!
No rust on the seat frame; The floor is free of oxidation, mildew and odor; The production date of the seat belt is within the vehicle factory date, and there is no deposit in the seat belt buckle; The fuse of instrument and electric box is not corroded; The skeleton of the center console naturally rusts; Based on the above points, we can rule out the suspicion that the vehicle is soaked in water.
The fixing screw of the main driver's seat has removal marks, which may cause many functions of the seat to fail. Occasionally, a small fault requires the seat to be removed, the assembly line to be repaired or the motor to be replaced. After testing, the seat function can be used normally.
Turn on the switch key instrument, and prompt that the headlight activation range is reversed. This fault will not affect the use of vehicles for the time being, and we will observe it slowly in the future.
There is abnormal noise when the left front door lifts the glass, like the sound of being caught by something. It is necessary to disassemble the door trim to see if there is anything inside.
The adjustment knob of the air conditioner on the right side of the rear row is stuck, and it is impossible to adjust the cold and hot conversion and air volume. To solve this problem, it may be necessary to replace the panel assembly, and the cost is about 2000 yuan. If you don't mind, there is no need to replace it.
The headlight cleaning function was tested and it was found that the headlight spraying water could not be used. To be honest, this function is not used much, and I don't think it is necessary to prepare it.
Connect the computer to detect the OBD electronic control system, and the faults of the central control and headlights cannot be eliminated. According to the function of fault codes, it is found that they can work normally, and the internal signal problem of control unit module does not affect the normal use.
Read the mileage of the gearbox, which is consistent with the mileage displayed by the odometer, indicating that the vehicle has not adjusted its meter.
When the trunk was opened, the small-sized spare tire did not land, the tools on the car were complete, and no traces such as sand collision, repair and gluing were found around the rear fender, thus eliminating the rear-end collision accident.
Get in the car and start the road test. Although the body is large, the power of 3.0T and the blessing of Quattor four-wheel drive make this Q7 drive have no tail feeling like a sailboat, the throttle is deep and the push back feeling is strong enough. When changing lines, the steering wheel is flexible, the suspension is soft and the braking is linear. After the overall road test, the chassis has no abnormal sound, no sudden shift, no deviation in direction, smooth and powerful oil supply and excellent sound insulation effect. The driving texture is still in line with the standard of the flagship SUV of that year.
During the road test, a complete maintenance record of this Q7 was sent from the backstage, showing that the front of the car had collided, several parts on the left front were replaced, and the upper longitudinal beam was also repaired. The upper longitudinal beam is the main structural part of the car body. If it is really repaired, this car is undoubtedly a major accident car.
I have tested the iron head before and found that the left front fender and water tank frame have been replaced. Now lift the chassis and carefully check the front longitudinal beam and the left front suspension!
After a detailed investigation of the left and right side longitudinal beams at the front of the vehicle main frame and their surroundings, it is found that the surface of the longitudinal beams is smooth and natural, and there is no bonding trace of sheet metal and plastic repair, and no longitudinal beam repair described in the maintenance record is found. So, this is another honey juice shop in 4 S.
A set of mechanical parts of the left front suspension was replaced, but the upper left headlight was not replaced, and no abnormal repair was found on the inner beam of the left front fender. I infer that the left front lower part of the iron head should have hit the bottom, but the beam was not injured, so it was not a major accident and the body structure was not damaged. Replacing vehicle parts has no potential safety hazard and will not bring any side effects to normal driving in the future. However, the ground clearance of Q7 is 205mm, and such a high chassis can last to the end, so there is no one.
There is oil leakage at the contact part of the engine gearbox, and no trace of disassembly and maintenance of the gearbox is found in the surrounding investigation. At present, the degree of leakage does not affect normal driving. If post-treatment, the project will be relatively large, and it is necessary to replace the bent oil seal after the gearbox has landed.
There is leakage in the front differential, which is also caused by the aging of the seal. This is not a big problem. If not handled properly, it is necessary to remove the differential and replace the oil seal. The maintenance cost of the above two parts is about 5000 yuan, and the materials are not expensive, but the working hours are more expensive.
The rear differential case is dry, free from disintegration and oil leakage, and the left and right axle shaft oil seals and dust covers are free from aging and cracks.
The rear anti-collision beam has no abnormal conditions such as deformation and bending due to disassembly collision, and the rear apron is flat and natural, further confirming that there is no collision accident at the tail.
Four-wheel tires have been replaced, the production date is 65438+22 weeks in 2008, and the tire tread is deep, at least 30,000 kilometers; The thickness of the brake pad is still more than half, so there is no need to prepare and replace it.
After checking the chassis, the test for more than two hours is over! Summarize the automobile condition:
Vehicle appearance inspection: hood, left front door, left rear fender, right front door, front bumper replacement, rear bumper and right front fender; The front windshield is damaged and cracked, so replace the left front fender;
Engine compartment inspection: the water tank rack is replaced, a set of parts on the left side is replaced, the oil is dirty, and the left and right valve covers are leaking oil;
In-vehicle inspection: remove the main driver's seat;
Vehicle start-up detection: no abnormality was found;
Vehicle function test: the left front door glass rises and falls abnormally, the right rear air conditioning control button is stuck and can't be used, the headlight cleaning can't be used, and the fault of OBD headlight central locking can't be eliminated;
Vehicle road test: no abnormality was found;
Vehicle chassis inspection: replace the claw, replace the left front shock absorber, replace the left front suspension parts, the engine gearbox joint leaks oil, the gearbox and the transfer box joint leaks oil, replace the tires, and the maintenance records show that the longitudinal beam repair is inconsistent with the actual situation, and replace the front accessories.
Send a summary of the car condition to the customer, and then explain it orally to the customer, telling him that there is a bottom collision in the left front part of this Q7, and some parts have been replaced, so it is necessary to pay attention to the oil leakage of the chassis. The customer knows the situation inside and outside the car, saying that our inspection is meticulous and comprehensive and found many problems. I didn't know how to bargain at first, but now the seller has good reason to reduce the price.
The manufacturer's guide price of this Q7 is 9,765,438+0.8 million, and the discount rate in that year was not small. All fall around 800,000. Today, the used car market is 270,000-300,000, and it has depreciated by 500,000 in six years. The seller offered 306,000 today. Considering the condition of the car, this offer is a bit high. I think there is at least 20 thousand room for concession, and I gave my customer an estimated price of 280 thousand. The customer took a swig of iced black tea and then went to bargain with the seller.
Today, when I was looking at the car, other buyers came to visit the steel-headed car, and I checked it. An older man told me in a low voice that used cars have deep water and car dealers are old hands. Many times, the law can do nothing for them. Doing this business is to fight against evil forces! Steel-toed, I replied with a smile, the evil forces were ten years ago, and now the country is cracking down on evil, not as black as you said! Grandpa shook his head and left, saying that you are still young! Readers, am I wrong? Although there are still many cheating phenomena, used cars are becoming more and more standardized, more and more open and transparent, and the overall forward trend is unstoppable!
