I'de buy another one gadget, but i've just sold mine to purchase a particular vehicle.

For anyone considering buying one, do it. Very good fun, not just the driving, but the challenge of setting up the kart. Tyres, toe settings, chassis, seats, engine, track width, and exhaust settings all contribute to putting down fast times. Very exhilerating if you've got a decent 2-stroke and a good track
