Steve, if you come out to California I'll let you take her for a spin! It has an 1800 Spider motor with a low rear end. The car scoots along just fine. Oh, and to improve your weekend just a little -> the sedan does have a little surface rust, but nothing to chronic though.
The wheels are off a Lancia Scorpion. However, the front bumper is off of a CC Coupe. The plan is to remove both bumpers and replace them with custom tube bumpers.
