The Street Machine Nationals car show is going on this weekend at the Minnesota State Fairgrounds in St. Paul. As the name suggests it was mainly domestics (lots of late model Challengers, Camaros, Mustangs, and Corvettes; not as many vintage cars as I would have liked). However, there were a few GRM-friendly vehicles that you just don't see any more (at least here in the rust belt): a really nice Chevy LUV pickup, a line of first generation RX-7s, and a nifty Opel GT that had a 3.4 liter GM V6 and four speed driveline transplant.
