If you have any cars in the game (especially undriven prize cars even) you can offer those up for trade in the Marketplace Forum and somebody may bite. Many of us have almost every if not every car in the game.
BTW in the right hand side table when viewing the cars in your garage the STANDARD ones that have:
0 switches
0 miles
0 wins
those are the desirable cars right now that you can offer for trade. Price doesnt matter as long as its less than 1million (you cant trade cars worth that much).
Its a fair trade for a 15k credit car and a 900k credit car because everyone is allowed only one trade a day. Pretty much making the trade values all the same (except premium cars because anyone can buy them out of the New Car Dealership)
