Some people work their way up, but usually either money (theirs or family etc) or sponsors. Though I don't care for drift racing at all, take Hulk and his son, b/c of their money and connections he was able to compete (with a Viper non the less) which made plenty of people pissed off b/c majority in that scene work their way on up from cars they built and maintained themselves with not much money etc.
Love the GT3RS, especially in Black with Orange, but kinda disappointed in the difference on track, just slightly better then GT3. I'd personally take a regular GT3 and send it to Manthey for some goodies
I don't think Skip Barber uses Vipers anymore do they? I know they have the SRT-8 Jeep there now, which is a f'n blast, fun friggen truck. Love racing, building the biz to the point where I can just race and race 24/7 lol. I'd kill to compete in Alms or the like.
edit - hell, he soulda just bought a Cup Car
