Pontiac Pavement Pounders Shootout SoCal Edition, Part I
The Drivers Owner Bio: Alan Mandella Pontiacs and drag racing have been a part of Alan Mandella's life for more than 40 years. The 61-year-old Fullerton, California, resident and grandfather purchased '65 and '67 GTOs new. He recently sold a '68 Goat, though he is contemplating buying it back. He also owns a '95 Grand Prix as a daily driver. He purchased his '74 Trans Am because, "I wanted an F-body after owning a number of GTOs." He reports that drag racing his T/A is his favorite Pontiac-oriented activity.
