Bought Chevrolet Impala in 2002 car had 5 miles on it and I put the 5 miles by test driving the car I wouldn't recommend anyone to by a Chevrolet. Chevrolet doesn't stand by their cars I had to replaces the intake gaskets and a catalytic and a water pump and this week I had to put a transmission in it this week and that cost me 2400 and Chevrolet would nt help us a all, Chevrolet said that it had to many miles on it what do they want for a car to have no miles on it I drive to work and back. I don't think Chevrolet should had to paid for the transmission but I would like them to help us and stand by a american made car.
