This is a Red Rock Hill Climb point-to-point on asphalt worth 210 Points towards the next Wristband, and $16K to the winner (not including bonuses).
Restrictions for this race are Class-A cars or below, manufactured in the United States before 1980.

I have to admit that so far this is the best race in the game - a massive collection of classic muscle cars from the world before the Internet, oh yeah! The road is wide the chokepoints few and the curves are, well, curves! So hit the gas man and go go go!
This is another point-to-point that is basically two different races -- the race through the pack, which can be tight, and then a more open race as you lead the way.
