Default 2003 Coupe (widebody) - Supercharged and more

This is formerly DNAST1's award-winning build. I purchased the car about a year ago or so. Just built a new house and bought momma a Lexus - I need to improve my cash position. Otherwise, no fricking way would I be selling this car.

If you are looking for an one-of-a-kind, well-built C5 that is very well-sorted and has all the bells and whistles, this car is for you. It is worth the read if you are looking for a car like this one.

Quick details: 2003; M6; LS1 383 stroker; supercharged; 644 rwhp; 27465 miles; brand new rubber (less than 200 miles on them); newly freshened top end + tune; Alpine with Car Play; price is $32,000; located in Shawnee, OK

Car has practically zero issues. Only item to convey is the rear turning signals don't blink. The sideview turning signals (yes, it has them) work just fine. I think it should be a simple wiring issue, just didn't get around to it since I was building the house. Other than that, this car is perfect.

That is one of the Nicest looking and Tastefully modded C5's around and if it had an automatic transmission, it would be sitting in Our garage! That's not a bad price either for what is done and into the car!

That Spiral Gray is a Really Nice color too especially with the carbon fiber wheels!

Good Luck with the sale! Someone is going to get a Fantastic looking car (it probably runs Great too)!
