Purchasing Car on "Car Sales"(Visit full web store) at NFS World(FAILED!!!)

I purchased Marussia B2 "Treasure Hunter" Edition in official website of Need for Speed World but when I play the game and went to "Change Car" ,the car that I purchased is not there, I went to "Car Dealer"(just in case)--went to "Purchase Car" and select GIFTS, I didn't see the Marussia B2 "Treasure Hunter" Edition. So can anyone help me with this situation?/How to get that car...because I spend 7,200 SB, and nothing happened! :'(
