One owner - and no vinyl roof - rare for 1973. http://www.ebay.com/itm/1973-Pontia...XE-/112298296159?_trksid=p2141725.m3641.l6368
In the early days up until late 70's you could order a new car exactly the way you wanted . Color choices carpet or floormat , tires , radio or not , vinyl or cloth and so on . Was nice having those options .
This one is really loaded up. Wish it had been left original. http://www.ebay.com/itm/1973-Pontiac-Grand-Prix/332131209293?_trksid=p2141725.c100338.m3726&_trkparms=aid=222007&algo=SIC.MBE&ao=1&asc=20150313114020&meid=43a79fe83ff54c1494324049d30f9c89&pid=100338&rk=1&rkt=29&sd=112298296159
