https://barnfinds.com/plain-brown-wrapper-1973-amc-ambassador-401/ I don't ever remember an ambassador 2 door. This is a pretty sharp looking car. The plaid interior is very 70's.
Are those marks across the High back of the C pillars vinyl top missing from covering leaded in markings on the top? Only issue I have with the car.
They were always interesting cars, the owner of a now closed parts store near me used to have a 69 very much like this one, but powered by a 390 V8, and with buckets seats and console. I always thought it was an interesting body style. I always liked the somewhat odd body lines on the rear 1/4's & C pillars. I believe 73 was the last year for the 2 door Ambassador, it was replaced in the model line up by the new for 74 2-door Matador.
