Alot of people don't stop and think that yes, you can buy a late model Mercedes for under $20,000. But on a 98 C230 with fairly low miles (40,000) at a price at $18,000, I think it is by far the best value car in it's class.
I got it new in Sept 1997 (1998 model year) for my wife, up to today only done 35000 Km (17500 miles). For all these years 13 years, only replace one sensor and small gasket. Replace the tires, because tires over 10 years should be replace.
A great car to own.
