Steve,
I don't know where on the east coast you are, but I know of a car here near Philadelphia for sale.
It is a nearly completed A&C (Antiques and Collectibles). It has a 460 big block, Tremec trans, etc... The car is about 75% done, all the parts are there. Every single part on that car is brand new. The owner researched the daylights out of every part he bought. It was built by a professional Cobra builder. I know about the car because the guy who built the car is also the mechanic who takes care of my car (and puts it back together after I whip up on it on the open track

). He has a fleet of about 15 or 20 Cobras that he maintains, as well as building them.
Anyhow, the owner of this car decided to bail out before the car was done. His wife is having a baby, so I think he didn't want to spend the money to finish the car. Check it out at
www.legendarycobra.com (there should be a link to the car for sale).
I'm not partial to any car, but I just happen to know this guy, the builder and the car very well. The builder is meticulous as anyone you will ever meet, so this car is done right.
Steve
