just take a car from c rank and upgrade it to the max of THE C RANK AND NOT TO B RANK, and add nitro to the car and just watch the opposision get blasted to kingdom com.
yea you wont get it easier then that, dont level up but max the car to its current level, after then make it a b car full spec in b races, it works with the unlimited nitro anyways.
god i love this game...
