2008 Chevrolet Corvette Z06 2dr Coupe (7.0L 8cyl 6M)
The engine in my 2008 Z06 427 Corvette destroyed itself at highway speeds when the intake and exhaust valves fell into the combustion chambers. The local chevy dealer told me it would cost $15,000 for a new engine. I sold the car and suffered a $30,000 loss. GM knows about the valve seal problem but has failed to do anything about it. The Corvette is a piece of crap don't buy it. I would only change my opinion if GM sent me a check for $15,000.
