Is this "Sport Compact Car" Magazine, or "Sport Compact Pro" Magazine, or just "Sport Compact" Magazine?
There's been a buttload of scams going around lately that "sponsor" people by giving them "$12,000 Sponsorships" and "55% off Parts". Most even make you pay an Application Fee.
The gist of it is that you call them up, they go out and buy the stuff and sell it to you at these incredible rates. The prices aren't bad, but the quality of the stuff you get is questionable, and most of the prices you can beat on your own if you look hard enough or know people.
Basically they're Wholesale Clubs like BJs or Same's Club. You pay a membership and get to take advantange of the discounts that they've worked to get. Some are good, some are bad. But it's not really a "Sponsorship" in the usual sense.
