I would like more engine choices. For instance, have a choice of the stock engine or a hot rod engine like the old 3 in 1 kits. All the '32 fords should have a stock engine included, a Falcon should include a Ford engine not just a BB Chevy, a'49 Mercury should have a flathead included along with the Caddy, a Sb and BB engine in all the Impalas and Novas, etc. etc. Also more tire choices instead of the same standard tires in almost all the kits. Oh, and more wheel choices along with stock hubcaps. And all this for a lower price. lol
