I purchased my 2005 Z51 Corvette almost 2 weeks ago now. Daytona Sunset Orange Metallic. I am told the previous owner put over $10000.00 into the engine and I believe it. This runs like mad. I am also told that it is now 525 horsepower on the dyno. I have never been in a car that sets you back in the seat like this one. The cornering is awesome. Absolutely love it.
