I always use 2 cars, either A.) the 1977 mustang cobra, if your strapped for cash in the beginning. Or B.) the 69 charger General Lee, this car can get you well into the 100K race range, put a supercharger on it, some nos, and just start putting in the Forced induction mods. Try to lvl up your driving skill and lvl up your driver skill for better boost and nos upgrades.
My question is what next?? The 590hp jaguar is what I want, however the 2000+ Viper is where I went, at 1051 hp now, and only 80% of it's power. Def need to tune, def out of creds..
