A gorgeous machine. https://appleton.craigslist.org/cto/d/neenah-1969-buick-riviera-gs/7023757800.html
It has potential. Unfortunately, after Buick finally got the engines right, it didn't take long until they started old manning a sporty gentleman's car with bench seats, column shifters and vinyl tops. Again, little attention is payed to decent photography. Why can't he just spend half a second throwing that clutter out?
That is beautiful! Wish there were some under hood shots or closer shots of the dash! Yes, I'm afraid once again we see the results of someone who attended the Otis Campbell School of Photography!
Yeppers, these are getting scarce and I think for what you get, these are a good buy, if bought correctly.
With the center rear gas tank I just assumed it was probably a sloppy fill job from one of those 5 gallon red jugs with the nasty pour spouts. The puddle is directly below the filler spout.
