Best car to race in need for speed carbon?

The fastest car in Need for Speed: Most Wanted (don't kill me for this) is the Fiat Punto at 247 mph. Now others may have gotten faster but I'm talking about the ps2 version with no trainers of course. I got the punto in the beginning and kept it through the whole game. I got every tuning part and in a speedtrap race on Ronnie #3 i blurted out my nos in the first trap and i got 247 mph.
