1971 and 1972 Buick GSX Information.

There is very little known about the 1971 and 1972 Buick GSX's due to the limited production of this car and fact that in 1971 and 1972 the GSX package was an option that could be purchased on the car for the entire year.  The option could also come on any GS from 350 CI to the Stage1 and vary in color and trim options. It is very difficult to identify these cars without paperwork.

1.  There were 124 1971 Buick GSX's built.
2.  There were 44 1972 Buick GSX's built.
3.  The VIN number is the same as a GS of the same year.
