Have the demo. It comes with 5 cars (all mod'd out): Lotus Elise, BMW M3 (E46), Dodge Viper SRT-10, and Nissan GTR (R35), and the Pagani Zonda F. There are two events on two tracks; Spa, and London. You have to earn five stars (the max) each race to gain access to the Zonda F. You earn 3 stars for pole finish on both and two other stars are awarded for different achievements in each event. In London its lead an entire lap, and beat lap time 1:30.000. In Spa its reach 149 MPH and beat lap time 2:50.00. I've done all stars without any real problem except the 1:30.00 London, I can't beat that for the life of me! The closest I've gotten (that I've been able to see the time for) is 1:34.5 with the Viper and 1:35 with the GTR. If anyone has any tricks please let me know!
