I'm looking at a 2001 s500. It has 150k but appears to be in great condition. I plan on taking it to a MB dealer tomorrow to have them go thru it. It has a few cosmetic things like a broken cup holder and struck sun visor. The radio did not turn on today, they clain it worked until today, they are looking at fuses and say they will fix it. What things should I be considering when pondering the deal? Is the radio a big deal ? They are asking 8000 for it. Leather is perfect and exterior is real good. Newer tires and rides awesome. Any thoughts would really help me.
