I have been looking to buy a C200. Am getting an Approved Used 2008 C200 Kompressor SE from Mercedes dealer. However, the accelaration on the car seems to be slow, and the gear changes (automatic) are jerky. I notice a difference from the other cars that I have test driven. The gear changes and accelartion difference is there in both [C]omfrot/ [S]tandard drive modes.

Dealer tells me two reasons not to worry (1) car has just come in, so their garage would go through before handing over and (2) automatic cars adjust to driving habit - previous driver would have liked a slow accelaration, and so not responding quickly to the accelaration/ jerky gear change.

Would appreciate advice on whether I should go ahead with the purchase. Price is better than other 2008 C200 on sale, so its tempting. Or is the price low because there is a bigger problem they are hiding and I would need to keep running to dealer?
Thanks in advace,
