Barbieri had my old car for sale a few months back, not sure if it sold. It is a 10 car chassis with an LS3 and S5.
I have had the pleasure of owning a few 2 and 4 seat Alumicraft ls cars, and currently building a 6200. If that purple mid engine had an LS and sequential, I would be all over it!
Good luck with your search. If you see any off market and you don't buy, please send them my way.
