Sorry guys, but what about the Kyosho Inferno GT2 that is coming out.
There a lot of "spec" classes showing up at tracks for the "new guys" to On-road racing. This class is designed not to break the bank and have fun racing On-road at a relatively low cost.
The Inferno GT is based in the Kyosho off-road buggy. Altered for On-road. They are tanks and they can take a beating unlike the Serpents and similar.
The Inferno GT2 has a really nice Corvette body and a Audi body. The cars should be available really soon. The GT's have been out for a couple of years. Kyosho Inferno GT's are not the fastest, but are the most realistic and running in the "spec" class, the competition is fairly close.
