Do you have a 2000 BMW Z3 M Roadster? One thing we recommend checking is the rear subframe mounting points/floor sheet metal. They can be weak and crack. This is a repair that needs to be caught early or the damage can be so bad it can total the vehicle. On this project, our BMW Master Tech Emil basically took the whole back of the car apart. The subframe had to be reinforced which can take up to 25-30 hours of labor. If you are looking for BMW subframe repair near Lexington Auto Engineering is your go-to shop.
