Im voting other and gonna pull a car outta my ass on this one too.
A 91-95 Acura Legend. Reason being: the car could be capable of alot, but needs people with the know how to make it. Seeing your work, it would be a very good platform, that has potential but is often overlooked.
The engine is a 3.2L and can be powerful, stock it moves the heavy car with everything in about 15seconds down the quarter.
I know its a long shot, but i thought Id give it a try.
