First, with only150,000 on hand, it's not appropriate to buy second-hand mercedes or Audi, drive it yourself or rent a wedding car!
Second, it's not appropriate for you to drive it yourself after you buy it: I don't care how much you pay for a second-hand Audi or Mercedes-Benz. This second-hand car is very expensive to use, and its insurance, spare parts and maintenance costs are very high, which is n times more expensive than other cars, followed by fuel consumption. This kind of car is full of large displacement and high fuel consumption; Since it is self-driving, it belongs to the nature of consumption, and the economy is the first consideration, so it is not suitable! By the way, I'll tell you an economic data: I bought a new Buick GL8 in 2003, and it's still in use, and the annual car maintenance cost exceeds 60,000 yuan.
Third, it is not appropriate to consider the wedding after purchase: the wedding is of a commercial nature, and whether the model is suitable depends on the market and market demand. No company has the final say, nor is it one or two. Or after you buy it, rent it to a wedding company, which is also one of the channels.
Through the above analysis, you will have a clear understanding. Whether to buy this used car or not depends on your decision!
