Of course it's a $60 game with about $700 worth of cars (in real dollars) to unlock. You can unlock them simply by racing, but a $1 million car will take you about 3 hours straight to afford - assuming you come 1st in every race and never have to buy another car. So that's 7 (5.5 hours for a front page McLaren) really too much if you just want to have fun driving cars you can never afford (like me!). The free spins mode includes about 2/3 of the cars in the game, and most of them you will never want to use. In addition, 10 is very nice in terms of mechanics, art design, graphics, sound and communication with Top Gear hosts.
