honestly, they look like the ultimate "spec class" car, but the idea of having to buy a car (even if it's only $109) then throw money at it to get it more durable or easier to work on for me is a deal breaker.. especially when i can buy a used pancar on ebay for next to nothing, race it for next to nothing and be as fast as anything on the track.. i like the concept though, just needs refinement..
