An old kyosho is better than most of the new buggys out today, the quality and workmanship is unmatched. Kyosho is heavily into high end racing and the R&D deparment work hard to keep there products in the winners cirlcle. Sounds like you might want to race, if so your best bet would be the 7.5 inferno but the mp6 would be great too, parts are still avilable.
