I had a bunch of Z3M Roadies and one S54 Z3M Coupe back in the day, all were absolutely wonderful machines. For the S52 cars, the big issue is the rear subframe, the oil pump nut, and the seat belt holders on the seats always, always break. The S54 cars had bad rod bearings as well, I had the rods in my 01 Z3MC escape onto the road one day when I was driving down the highway. Luckily it was a known issue then so warranty took care of it no question.
As long as the car is in decent shape, I couldn't recommend it enough. Not sure I'd be so happy paying $30k for a car that old, however, I wouldn't even consider it over $15k. I'll duck out now before the MCoupe Mafia shows up and starts bombarding my DM box. Worst thing I ever said on those forums back in the day was I preferred the Roadster.
