Hello, the building owner, Mercedes-Benz E320 is a v6 engine, and the new 5 Series corresponding to it should be the 540Li executive version with inline six-cylinder turbocharged. Moreover, this BMW does not provide four-wheel drive, and Mercedes-Benz E320 comes standard with four-wheel drive. Two-car BMW is better, and BMW consumes less fuel. The new generation of 5 Series also has a qualitative improvement in the interior, with better comfort, even better than Mercedes-Benz. The new E320 is under control. Matching the new 9-speed gearbox, these two cars have different opinions, depending on the needs of the landlord. The brands of the two cars are equal, and they are century-old rivals. I hope I can help the landlord and adopt them. I wish the landlord an early car!
