Hello Forum,
Extensively modded 2003 QS C5Z looking for its next discerning owner. Clean title with zero accidents. All modifications were simply done for personal enjoyment. This C5Z06 has NEVER seen a drag strip or track day. Perfect 5th Gen Corvette ready to be enjoyed by the next owner for years to come. I purchased this vehicle in December 2015, around the time when most engine/suspension/aesthetics work were done, and all has been 100% reliable. All work has been performed by reputable Corvette-focused shops. Bulletproof mechanically and comes with no surprises. Originally a CA car and is currently located in North Texas.

Estimated 460 RWHP /390 RWTQ, no documentation but was dyno’ed at TPS Motorsports prior to the addition of the Borla quad-tips cat-back exhaust. The engine note at Wide Open Throttle (WOT) is simply V8 American Muscle Car perfection.
