I might see one 1976 or older Mopar every 2-3 days. I'm on the road 8-6 though. A 73-76 A-body more often. It really depends on the neighborhood I'm in.
Hollywood, Los Feliz, older beach communities, driving up coast to Santa Barbera, and rougher neighborhoods is where I see them most. Don't see many older cars out in fresh newer suburbs.
Various drives on the way to Santa Barbera...
** That BMW Alpina was really cool. Not just you regular old BMW 2002 you see putting around.
