Own a 1999 slk230 with 170K miles for 19 years now. . Its been a a fun car and is showing its wear. Thus due to the ease of working on this model we are starting to make it look new. New seat covers, door panels, headliner and perhaps even new exterior paint. Past problems have been the roof cylinders, K40 relay and fuel system. Put on new shocks and struts and had the rims re painted. My wife and I are in our mid 60's now but you know it will more then be with us and willed to someone! Hahah
