I am about to buy a 2002 CLK 320, the owner says the car chokes when accelerating and the check engine light shows up, also white smoke comes out. I want to know if this is a serious problem, and i want to know what are the main problems with the car and is it costly to maintain.

Thanx

 

Dear mdsaif:
I think your car may be air mass (minor) or engine mechanical problem (serious)
