I am thinking of buying a 2001 CLK430 cabriolet from a private party. The car has 150,000 miles on it and looks nice. The top was replaced last year. I took it for a test drive, everything works, no CELs.

I did notice two issues.

First, the car seems to wallow around like an old cadillac, which I assume means the shocks are worn out. How difficult and how costly is it to replace the shocks on one of these.

Second, no matter which direction I pressed on the power seat control, the seat moved forward until I feared I would be crushed against the steering wheel.

Asking price is $3,500. Any advice would be greatly appreciated
