This badass Buick Somerset, built by Tommy Riggins, has a racing past that reaches back into the 80's. It was built for the IMSA's Kelly American Challenge in 1985, and also ran in 24 Hours of LeMans and 12 Hours of Sebring in 1987. Its Chevy 358 makes 750 horsepower, and owner Shaun now races it in SCCA events at Laguna Seca. On his ride page, Shaun's got some hilarious video of it leaving the rest of the vintage racers in the dust. Listen to that engine!
