Yes, it was an SS350... the car in that ad was actually photographed by Don himself behind the dealership. He sent copies to various network dealers to use for advertising and promotion. I have all the original shots of the car, including the one used in the Humphrey's ad. Here's a few other outtake photos from the same photo shoot. Seems they couldn't decide whether to leave the headlights open or closed! Note the pic selected for the ads is marked with a #6... pretty sure that meant Don wanted 6 copies printed of that particular shot. Not sure what the "H" signifies on the other photo, Humphrey's maybe? Who knows!?
