I haven't been to the good guys show either. From what Ive heard it has alot more modified cars.

Here's what it says on the website



More than 3,000 custom and modified cars of every variety and color will be at Lowe’s Motor Speedway for the 12th annual GoodGuys Southeastern Nationals, October 28 – 30.

The street rod is alive and well in America. Most cars displayed at the GoodGuys show are driven – not trailered – to the infield of the superspeedway for three days of fun and reminiscing. Street Rods, custom rods, street machines and muscle cars are displayed at the show. Other features of the event include the GoodGuys GoodTimes Garage, where manufacturers give demonstrations of their latest products; the GoodGuys Young Guys club display, where rodders 25 years of age and younger show off their work; and a pedal car show for kids.
