This one finishes shortly, but keep an eye out for future ones as it's a good way to be in for a chance of getting a 'unicorn car'. And if your going to have a crack at this one, buy the Merc 190e and buy the tune done by someone who's gamer tag starts with F14, search as most downlaoded and it'll be somewhere near the top.

I only found out about these last month but I managed to beat the posted time for that and got the RX-7 spirt r type a. And I also managed to get the S204 just for correctly guessing one of the cars to be realesed in the August DLC!
