Factory Five GTM
You want an American supercar on a budget and maybe even to assemble it yourself. The famous kit car company Factory Five Racing has just the car for you. It is called the Factory Five GTM and it’s a very capable supercar you can build in your garage. The manual is part of the package, of course. Factory Five Racing is best known for its Shelby Cobra kits which are quality reproductions that enthusiasts love. However, the company made a move to the supercar market with the GTM in 2007 (via Factory Five).

This is a very modern car with a Kevlar body and aluminum chassis powered by the Corvette’s V8 engine. Also, lots of components like the drivetrain and suspension are derived from the Corvette, making it cheap and easy to work on and maintain. Due to its lightness and power, the GTM is fast with 0 to 60 mph times of around 3 seconds and a top speed of over 180 mph. Also, it’s quite affordable as the basic GTM kit costs just $24,900. Remember that you will have to provide the Corvette engine and drivetrain to make the GTM roadworthy.
