1973-5 Plymouth Duster. The "Gold" package had a number of options, from the picture it appears this one had the gold badges, the [now missing] vinyl roof, and the vertical rubber bump stops on the front bumper. Based only on production numbers, odds would have it that one came with a 255ci slant-six. Less likely would be a 340, even less likely a 360.
Not a particularly attractive car, but it is a decent platform for a small block MoPar. I would take one - I've had a 360 patiently waiting for a home for almost 10yrs...
