http://www.justdashes.com/gto_2005.htm which shows the same car, minus the front plate. There weren't many of these made, and to see both of these with the same tires, paint, and rims, in So Cal, is more than coincidence I believe
Umm, the reason it's cool that it's likely Jim Wangers' car is that he is an icon of Pontiac muscle cars.
