Incredible that you mention the 76 Grand Prix SJ. Because, last evening, just prior to coming upon this thread, I was at a local muscle car and classics car show here in Queens NY, at Aqueduct Racetrack in Ozone Park (former Goodfellas country), and saw the most gorgeous late 70s Grand Prix I had ever seen. And I was in my twenties during the peak of the disco period when these cars were, as they say, the joint, so Ive seen plenty. In fact I owned at the time an especially nice '73 Buick Regal. It was white with burgundy interior and burgundy padded landau (half)top. I say "especially nice", because I never considered the Regal to be as stylish as the GP, Monte Carlo, or Cutlass Supreme. However, mine did standout from most.
A good friend and drummer of the garage band I was in (I played bass) owned a 75 or 76 GP, gold with t-tops. Beautiful car. A jockey friend of mine had a white Monte Carlo with white interior and t-tops. He later went on to tie a jockey record for most times having the most wins in a season at Finger Lakes racetrack in Upstate NY...9 times I believe it was.
Anyway, have always loved the Grand Prix. Growing up on the Lower East Side of Manhattan in the 1960s, my brother owned a 64. But getting back to the '77 I saw last evening at the local show, here is a pic of a '76 that is very similar. Same dark blue, same beautiful white interior, same bucket seats, same t-tops, same "SJ" badging, etc.
***just remembered after typing all this that I actually took some photos of the one I saw last night. Will post those after these.

Here is the actual one I saw and photoed last night. IMO, the 2-inch whitewall tires and spoke chrome rims on this one puts it over the top--even better than that first one I posted.
A few years ago it locked up and she stored it in my pole barn. I bought it and dropped a 350 4 bolt in I had laying about. She's been after me to get it back. Not gonna happen. LOL.
When I see a Grand Prix all I can think of is Pimpmobile.
The one you saw last night was a ‘77. The one posted above it was a 76. Mine was 76 and with the exception of being White, had the same features as the one you posted. Thanks for bringing back a great memory!
