hey guys...i really need a little help here...you see i raced in the endurance hall under grand valley 300 km and i was hoping to get the mercedez benz C9 sauber as a prize car. however after i won the race, i got an auto union streamlined race car that dates back to the 1940's or something. i tried to race again and won for the second time hoping that the prize car would change, but it didn't...what seems to be the problem? pls, if anybody has the same experience of knows how to obtain the the mercedez sauber in any other way, i would really like to hear you...thanks guys...hope someone could help...
