Hey Keith, when I was growing up in Detorit, there used to be (and these are really fuzzy memories) Art Moran Pontiac, along with (I think) Roger Penske Chevrolet, and a Chrysler/Plymouth dealership all within a stone's throw of one another, on 12-mile road? I seem to recall them being around the Tel-Twelve Mall. I remember back in 1973, we looked at a new white 73 SD-455 Trans Am parked in front of the Art Moran Pontiac showroom, and I recall seeing an Indy race car parked in the Penske showroom. My oldest brother said there was a "road to nowhere" that ran next to the Chrysler dealership, marked off for a 1/4 mile, with a turnaround at the far end.
I found these pics of a Los Angeles dealer called Majestic Pontiac. You can see how the sign was in decent shape a few years ago, deteriorated over the years, and finally into the 2009 symbol of traditional Americana : a Sporting Goods store, a Denny's, and a Goodwill center.
