non amg '85 500sl here. have the spoiler, did have the stock exhaust until upgraded. If I recall correctly my car is an inch or 2 lower than American models, other than that I don't know. Imported by my family and picked up in houston. Is there any engine performance difference other than the exhaust from amgs?
