Having driven a Shelby GT500 for 30 years, my standards are high. The C5 met them readily, and just keeps getting better. Average 24 MPG, highway of 30 MPG at 70 MPH. I'm a big guy, and the car fits well. Active Handling is fabulous, the sound system is great, and it looks incredible. While the Z06 of a couple of years later is more powerful, I like the fastback look, and can mostly have a convertible when I want. Great car for the money - less than a Civic Hybrid, and the MPG is great for a 13.5 second quarter miler with a top speed north of 170.
Active handling, Bose sound, LS1 engine, transaxle/weight distribution.
The windshield header squeaks a little. The original "wagon wheels" are a bit funky (I replaced with Z06 wheels). The cup holder is a joke, but who needs a cup holder in a Corvette? Better left out. Wait - it holds my cell phone! Guess it isn't so bad after all.
