I have an '04 W220 (S430) and it's been a very good and reliable vehicle, although it is nightmarishly complex and expensive when it does need repair. I'm thinking of a roadster for weekends and summer trips. I don't really want another complex and expensive vehicle, so the SL is not what I'm considering. The SLK seems a pretty good combination of affordability, sport, relative simplicity, and a hard roof. I've looked for the answer but had no luck on the search function. How about it guys...which version to buy, what to look out for, and where are the problems? I've qualified for IMSA and SCCA competition licenses (expired long ago), so I'm not necessarily going to be an easy driver. I maintain my cars meticulously, and they are repaired to the factory specs. Help me out.
