This Clear Springs Sprint is a 3-Lap Circuit Race on Asphalt and pays 150 Points towards the next Wristband and $11K to the winner (not including bonuses).
Restrictions for this race include Class-A cars or below, and they must be manufactured by Dodge.
This race basically means using the Charger or the Challenger -- you should have a 2012 Charger SRT8 and a 2012 Challenger SRT8 392 in your garage, but you can also head to the Auto Show and purchase a 1969 Charger R/T (the same model as the General Lee) for $64K.
If you really like the classics that might be the way to go...
