Scott Oldham does a deep dive on Phil Roitman’s rare – and extremely well done – ’73 BUICK: STAGE 1 455 GRAN SPORT, one of the quickest, fastest and most forgotten Musclecars of the 1970s!


Buick’s public relations department was asleep at the wheel in 1973. Although the brand’s Gran Sport Stage 1 was among the stoutest of the remaining midsize muscle cars offered that year, it was largely ignored by most of the major contemporary car magazines. Car and Driver, Road & Track, Hot Rod, and others failed to publish road tests of the GS, which offered more cubic inches, horsepower and torque than almost anything else coming out of Motown.

In the October 1972 issue, the publication called out the 1973 GS Stage 1 as one of Detroit’s best buys, along with the AMC Hornet Hatchback, Chevy’s Camaro LT, Ford’s Pinto Wagon, and the Pontiac GTO.
