Not mine, but looks like a good deal to me. It would be nice to see more pics...looks like ad was posted by a little old lady based on the farcebook pics in the link she posted and being original owner car. https://pensacola.craigslist.org/cto/d/navarre-1972-pontiac-grand-prix/7310352097.html
I have owned a 1971 and a 1972 and parted several of these GP's. Nice driving cars but unfortunately don't bring much money especially a low option car. Interior pictures would be nice. Several parts are hard to find and expensive if damaged or missing which is sometimes a downside to owning these cars.
I had a buddy in high school who decided to get on his 400 Pontiac gp in the rain and lost it jumping a curb and taking out an entire row of new chevrolets at the local dealer. It was a nice car.
