Goodguys Communications Director John Drummond said that with a forecast of sunny skies and temperatures in the upper 70s, it's likely the show will attract record crowds. For that reason, extra traffic control personnel have been hired to help deal with overflow crowds.
The Goodguys event, presented by Specialty Sales Classics, is California's largest two-day automotive event. It will feature indoor and outdoor car shows with more than 3,500 hot rods, custom cars, classics, trucks, muscle cars and street machines of all years, makes and models.
It also features a swap meet, a cars for sale corral and vendor exhibits.
Entertainment at the show will include a Goodguys AutoCross road course, free kids games and live music, including more than 25 live bands gathering to participate in the Diablo Valley College "Rhythm, Rock & Blues Review."
On Saturday, more than 40 highly customized cars from the 1930s through 1972 will be showcased inside the main Fairgrounds building competing for the Goodguys 2013 Mother's Custom Car of the Year Award.
