You have a glitch here. i can win any race to unlock a part, even 10 times the first one xD

NICE GAME BUT VERY SHORTLY !!!!!!

Good game, maybe a few more levels and another vehicle extra might add some more variety to it.

Other then that, I love it, so 4 stars!

good graphics, poor sound

the graphics were very good; the scoring and upgrade-unlocking systems were bland, and the sound was really bad. First, the background loop was much too short; and then the roar-like sound (which is the only sound in the game) that plays throughout all race was just annoying

Not bad, but not great

Aside from the helpful comments already listed, no one would take a front wheel drive truck into a mountain! Make the truck all wheel drive!
