History. In the spirit of full disclosure here's the story on this car (which I've owned twice). Traded my '06 C6 A6 for the Z06 back in the fall of 2009 at a local Chevy dealer. In the fall of 2010 I had a fender bender that lightly damaged the driver's front corner of the car (see pics later in thread). I had a friend that wanted the car as is so took his modded C5 on trade + boot. He fixed the car with a used GM factory carbon fiber fender & a new GM nose then had the paint blended to match. Paint match is perfect as shown in pics. After a few months of driving the car he did a cam swap & 2 weeks later an exhaust valve broke which trashed one head, one piston & a cylinder liner in the stock LS7. He was in the process of buying a house so the car sat until the fall of 2011 when I traded a different modded C5 + boot to get it back. I sold what was left of the stock LS7 motor & bought the LSx block Mast Headed motor complete from a guy off VetteForum. Car has clean title but the accident history does show on Carfax.

Performance. Car has run best of 10.98 @ 129.4 in the heat on a soft 4,500 rpm launch with a 1.74 60'. With a higher launch & some good air car should 60' in the mid 1.5's & run mid 10's all day long. This setup runs good NA, but it is begging for a power adder to take full advantage of the flow capacity of the Mast Heads. I had intended to put on a nitrous kit this fall & try to run some 9's. Driveability is good for a cammed car, can lug 6th gear at 60mph with no surging. Car can be daily driven & you could head to California with it for a road trip if you wanted.

Condition. Car is nice but has been driven & enjoyed so it has a few character marks. Interior is nice, no issues. There are some paint chips on the nose of the car. They don't stand out from 5' away but when you start washing & waxing you notice them. Also some chips around the rear brake duct inlets. I've never had anyone notice or comment on paint chips. Also the front passenger side corner of the hatch is damaged where it meets up with the 1/4 panel. I think maybe the rear hatch needs to be adjusted back an 1/8" or so to increase the gap. I attempted to show pics of all the defects mentioned.

Car is located in Lexington, KY. SOLD!!!. Also please don't PM me asking my best price, if you have an offer please send it & I will respond promptly.

Here's a few iPhone pics & an idle vid:

This car has had all the typical C6Z06/LS7 weak points addressed. The LSx block is good to 2500 hp so no weak Aluminum block cracked sleeve issues to worry about NA or with a power adder. The Mast heads have one piece stainless valves so no broken two piece valves to worry about. The weak stock clutch has been replaced with the ceramic twin disk & remote speed bleeder so no clutch pedal stuck to the floor or slipping issues. Also no worries about broken rear axle shafts with the upgraded C5 shafts.
