Problems with my 2002 SLK320

Here is a list of problems I have had and I am currently having; 1. Antenna had to be replaced twice (don't let it get loose), interior fill up with smoke - Heater/AC blower motor bad, Heater/AC regulator needs replaced, Left side sunvisor has been replace 3 times, steering damper replaced, the roof is now starting to leak, power seats don't always work - not sure of the problem as it comes and goes, alt and voltage regulator needs replaced. Current mileage 50,000.
This doesn't include the normal replacement parts like; brakes, tires........
We should all understand that we might have bought a Mercedes but we really got was a Chrysler product!
