If you want some thing that will take care of the Itch. Why not a kit car? Race car replicas has about 6-8 cars. They have some old style Porsche. Ferrari, GT40, a open wheel car, and what they call the SLC. That is what I would love to build in a few years. The SLC has been fitted with small 3 rotors all the way up to v-12 motors. Also Factory five has some good kit cars. They mostly have cobras, Daytonas, and a GTM super car. They even have a old 30 something ford coupe.
RCR's cars are pretty munch a giant lego set. You don't need to source any thing other then a engine, transaxel, and wheels. The wheels are only if you don't want the factory ones. They use corvette lug pattern. So it is easy to find wheels. The bodies from RCR are gel coat also. So you don't have to paint them if you don't want to. The bodies come in like 12 different colors. While factory Five you have to source every thing. Most of there cars use ford parts. The GTM uses vette parts. They now have a car that uses a Subaru for a donor. I have heard many people spend over 100 hours on the Factory five bodies alone. Vs just a sand and buff job on the RCR bodies.
