Pretty Low option car, probably a 400 2bbl, with auto trans. But looks good from the pictures. Not my Favorite colors, but I could live with it. The only options I see are Power Steering & Brakes, A/C, & Rally Gauges with Clock. I know the Rally II wheels were the base wheels on a G/A, as were the Sport Mirrors. https://kansascity.craigslist.org/cto/d/kansas-city-pontiac-grand-am/6903513489.html
The big thing--the header panel--appears to be intact and in good condition. Imagine how this car would look if it were fully detailed.
The only issue is if it is the original header panel, how long will it hold up? I knew a guy that had a NOS one stored in the original box in his basement, and if fell apart during storage.
Then this may be a unicorn waiting to fall apart. It's too bad the repros aren't made from the current Enduraflex formulation.
It's also got rear defrost with the 80A alternator, which is pretty nice. That is a 2bbl air cleaner so you know it is one. The power steering and brakes and gauge panel were all standard on the Grand Am so other than rear defrost and AC, it's pretty sparse! I did love mine that I drove every day 15 years ago.
