Another fact to keep in mind are these cars are 12 to 16 years old so things will go bad. The good is almost any issue has been dealt with and there are solutions and help mon this site. NEVER, NEVER go to a dealer. If you must use a mechanic use and independent shop that knows Mercedes. Mechanically these are SLK 320s.
