 We bought our C240 preowned back in Dec 07. So far, there have been several issues. Cup holder had to be replaced as well as both rear door outside handles. Now there is an issue with catalytic converter. Dealer says it may be defective. Car had 24K miles when we bought it. Now has 28K miles. Love the way the car looks and interior, but not sure about quality. Gas mileage not that great either. We traded in a 99 230 compressor which was a better overall car. Not sure if we would buy Merc Benz again.
