1971 GS Convertible picture, also taken right from the 1971 Buick Brochure.
Note that is shows bucket seats installed, yet bucket seats were not available on
GS convertibles in 71 and 72!! A couple convertibles were built though with buckets as special
SCO orders.
1972 GS Review by Hot Rod Magazine, September 1971 issue (check
out that price, in 2020 dollars that would be just over 28,730.00)
1972 GS 350 (note hood tach on this car, what appear to be incorrect (ie 1970 style) centercaps, rear seat shoulder belts, and blacked out grille/scoops/headlight bezels. There is some debate as to actual colors used (black vs dark argent) but pictures can show either depending on saturation, etc). GM photo (cropped).
Sample of options shown in the 1971 Buick Brochure:
Here is a copy of an original Revision 1 Buick GS car order form from
1972, thanks to Stanley F. for providing me with this. On the backside are suggested
color combos and engine information. I laughed when I saw the saddle interior was
available but was not a recommended color combination for my convertible. No Kidding!!
Take a real close look at some of the car photographs and it is quite obvious that
fit and finish were not the most important items on the list and nobody cared, don't forget the technology of the time was not that great. Thats why most cars you see
at car shows have been put together much too carefully! Also note that all the cars
on this page have vinyl roofs, it was a popular option. It was a very curious period
of car production where the models spoke for themselves and there were more interesting
things to do with the vehicles than comparing door gaps and cupholders.
