| The 2008 corvette with auto transmission , fails to accelerate after slowing down to a stop light or turn. there is quite a lag b4 the car gets going. had it to the dealer 7 times. will go after the florida lemon law, since gm says it is normal to expect lag and hesitation from a corvette. this is not only bad for the top american sports car but a safety issue as well. hopefully gm will do the right thing and refund me my money at the lemon law hearing and trash the car b4 someone gets killed in it. this has happened since i bought the car and it now has 21000 miles that have not been enjoyable. stay away from 2008 corvettes with auto transmissions. *tr | |||
