DLC is downloadable content. I pre-ordered from GameStop and they put the code for my Stealth cars on the receipt. If you didn't pre-order, you won't get the Stealth cars, unless they release them on the PSN.
Yeah, only if you placed an order for the game, before it was released. You would get stealth car as a bonus. I pre-ordered my game in September, from Amazon, and they had a deal for a Stealth Mercedes SLS.
DLC stands for Downloadable Content, which is basically extra content which companies put out, like extra maps, or cars, tracks, most of the time for a fee.
Im selling one on ebay. I could of sold my NSX for around 50 dollars but decided to keep. My ebay seller name is freddybanuelos89. The Mercedes SLS auction is about to end but i will be having 10 Nissan GT-R's for auction one by one
