Yeah you can buy a on-road car and that will beat the Jato. But if you want a ST to beat the Jato for top speed then you will have to buy one. If he has a stock Jato then it wont be that hard to suprass him in speed as all you would need is a larger engine and a little re-gearing of the engine and that should have you getting off the line faster then him along with a faster top speed for that WOW factor.
