Exterior: Black. This car has always been maintained on time, and it is used with great care. After a road test, the overall power and braking of the vehicle are still very awesome, and the chassis support on curves and bumpy roads is also very good. Overall, this car is still a good performer. In the domestic market of medium-to-large luxury three-box cars, the BMW 5 Series can definitely be considered an excellent classic model. The solid chassis created by the front double wishbone and rear multi-link suspension, combined with BMW's consistent high-rigidity body and lightweight aluminum alloy parts, gives you absolute confidence when turning corners. I was attracted by the low-key style of the BMW 5 Series. In China, its competitors, the Mercedes-Benz E-Class and Audi A6L, are all business cars, suspected of being "official cars", while the BMW 5 Series focuses more on driving pleasure and has stronger driving controllability than the other two competitors.
