Bought this car still under factory warrenty. Immediately the lifters started knocking, interior rattled, muffler began making an obnoxious rattle. Right after Chevy sent a notice that the head gaskets were defective the engine blew up. Next engine has had nothing but problems - emissions and drivability. 2 dealers and 1 independant shop cannot figure it out.
When I think of one I'll let you know. There is a reason it is consistantly on Consumer Reports list of cars to avoid.
Scap the antiquated j-body. Send TSB's to owners of vehicles. Dealerships obviously ignore TSB's and try to get you to pay many thousands of dollars in repairs on a guess and parts swap scheme.
