Rare to see one of these without a vinyl roof. I like the clean look. 1976 Pontiac Grand Prix 23,639 Miles 350 V8 - cars & trucks - by... (craigslist.org)
Its a nice looker, and really well equipped for a "Base Model" GP, with the 350 2bbl engine and bench seat, A/C, Power Windows, Locks, & Bench Seat, Tilt, Gauge Package, Delux seat belts, Body Colored Rally wheels (but the trim rings don't look right for the year), bumper rub strips, Duel sport mirrors (drivers remote), but only an AM Radio, and no Cruise Control. Nice car, but $30K asking price? Dreams, Dreams, Dreams........
I'm with Jeff. Nice car with a decent set of options, but $30k is a pretty tall ask. At least it's not a 301 car like was available in 1977. The trim rings on the wheels are early '70s rally II trim rings I think (like '71-72).
