Not gonna happen. The idea behind buying this car was because it was cheap, reliable and gets good mileage. As far as I am concerened these kids triyng to make hot rods out of these cars is just rediculous!
Good vehicles are expensive. Maybe you can afford a Chinese copy. lol. I would rather have a Aptera 2h 3 wheel hybrid car that is projected to get 300 mpg. But my guess is that a new Yaris will be cheaper to buy and more fuctional. Of course you could add a turbo to your Yaris and get another 25 HP from you Yaris. lol
