Start taking all the licenses accept for the rally-license - it's not sp important. then you buy a mazda mx5 at 16,900.-. win sunday- and clubman cup, sell the trueno's you'll win, and buy a turbostage 2 to your mazda. then, drive the fr-cup in beginner league and you'll win a mazda mx5 1.8 at 160hp. then drive the endurance for non-tuned mazdas. tere, you'll win 100.000 and then buy a dodge viper gts! give it a na-tuning stage 3, and drive 'like the wind' in proffesional league. you win a mazda 787b! then you have just established yourself one of the best cars in 4-5 hours.
that's my advice for you! =)
