Looks sweet to me.
Its basically a Miata engine in these things, so that means they turbo very easily and it already would have a wide variety of aftermarket.
SO lets say you put on a nice turbo (3,000) with some bolt ons and a manual boost controller(~1,500) and I'm willign to bet it would perform better than a WRX for about the same price. I love the suspension, I'm gonna test one of these little things out soon.
