DF Kit Car: Modern mid-engine kit cars If you can pick up the kit from the factory in its cheapest form and find a cheap donor Cobalt should be able to build it for ~10k. Going for the turbo engine with all the options still shouldn't pass 20k by too much even if you had to get it via frieght. The utilization of the donor Cobalt is incredibly extensive and will also make this very easy to maintain. Also looks like one of the few kits that won't surprise you with a bunch of fabrication work you didn't expect. Granted it isnt much to look at and can only be fair weather driven. But 0-60 can range from under 5 to under 3.5 for the turbo if you can maintain traction. Doubt it has stellar handling but I'd bet it would be a blast to drive.
