Before we traded in our Cobalt SS for the new Camaro, we spent about the same on maintenance for both cars, with the one exception being for oil changes, synthetic oil changes are of course more than regular ones. We still own our 2005 Vette, bought it new and haven't had any problems with it, has about 45k miles on it and we are still very happy with it. I think you will be very happy with your purchase!
