I have a great sponsor for my car. He covers all the costs (parts and labor). Paypal me $100 bucks and I'll refer you to him. He's here on H-A and drives a red G35. Great guy :thumbup:
But seriously, go to shows, lots of shows, start modifying your car. Get some awards, be come known, it's when companies will start thinking about you. But they'll won't cover EVERYTHING. Just fraction of costs.
