Seems pretty amazing now, but particularly in the Valley, there were competing dealerships only a few miles apart; such was the appetite for new cars.
A lot of major boulevards would have several different dealerships - the "auto row" - and it was fun to wander through them and check out the cars.
I would entertain myself for hours with that sometimes; window-shopping, grabbing brochures, and then strolling over to the next place.
The used-car lots would also have some pretty cool stuff - basically the previous New Thing - or older hot cars presumably sold/traded for factory muscle.
