You shouldn't worry, the G can take out Hyundai Accents!
Btw, I think that if your sole reason for buying a car, let a lone a G, was to race, then you should have invested in something faster. Of course, you can make the G faster, by adding a turbo etc - but if you wanted to race, why not just go out and buy a WRX or a turbo SAAB
.
I'm not into racing - so I could care less about the G having 140 hp.
