CTS-V, 89.830
There's a lot left in it. This is just a quick build and a sloppy lap. I expect to drop about half a second off it by slapping on a proper tune and driving a decent lap.
(edited for new time)
Update: Slapped ona blooze toon. It's a decent car at this point, but a little ill-mannered. Also, it's 3800 lbs. May start a second car soon.
