Would a 1990 300sl hardtop fit any 90-02 SL? What would I expect to pay for one that was in great condition with everything I need?

 

I believe the early hard tops were modified in about 94-95 to allow for a different window trim configuration. You should try and find one which matches your year.

I purchased a great top on EBay, which usually has several available at any one time. Be aware that shipping is very expensive!!

Good luck!
