1968 Buick Gran Sport

While the GS 350 appeared like the Skylark Custom on the inside, it had a more muscular appearance on the outside. All vinyl foam padded seats were standard equipment and bucket seats were optional. To identify, there is a GS 350 plaque on the center of the deck lid as well as the grille, door panels and rear fenders. There was also a "California GS" that was similar to the GS 350 but included a deluxe steering wheel, vinyl roof covering, Super Sport wheels, California script with GS emblems on the grille, roof panels and rear fenders. Among the standard features on the California GS were all vinyl seating, vent windows, chrome exterior tram and 2-speed automatic transmission.

The GS 400 could be identified by the GS 400 plaque on each front fender. Features included fake fender vents and functional hood scoops, folding seatback latches, all vinyl bench front seating, optional bucket seats and F70 x 14 wide tires.

Gran Sport equipment could be ordered on the Riviera which consisted of heavy duty front and rear suspensions, H70 x 15 red or white stripe tires, and positive track differential. The Gran Sport could be identified by the GS signature on the instrument panel as well as front fender GS monograms.

In a wake to the muscle car performance market, Buick quietly introduced a rare dealer installed option in 1968 called the "Stage 1 Special Package" which optioned the 400 cid engine with a hotter cam, 11.0:1 compression, stronger valve springs and a reworked transmission. Officially marked at a 345hp, most experts claim that it was more like 390hp and it dropped 1/4 mile times by 1 second or more. As Muscle cars were on the rise, it was a great indication of more performance that was yet to come.
