Overview: What is a Pro Street car? Basically, it's just a car with a tubbed rear end that allows for bigger tires. But this time on Roadkill, it means so much more to Freiburger and Finnegan as they take a big-block 1980 Mirada on a road trip to the site of the Street Machine Nationals in Du Quoin, Illinois. Is this Pro Street Mirada fast? No. Does it handle well? No. Does it look obnoxiously awesome? Of course.
