When I take off the gas is sticky and takes alot to get it going, when turning from stop my rear end vibrates like it's going to fall off. Aready had the transmission replaced by the dealer ship I got the car from. Driver side window clunks when rolling down, motor makes a knocking noise when cold. I just don't expect this kind of problems when you pay alot of money for a nice car.
