I admit it. We have now come to my very favorite muscle cars of all, the formidable 1970 Buick GSX, with or without the Stage 1 options upgrade. My very first car was a 1970 Buick Skylark (about which I’ve already written) and it shared the same body and general appearance of the GSX. Of course, it wasn’t nearly as fast or as tight a package, but that’s OK. I only paid $500 for it. In my eyes, the Buick GSX is THE ultimate Muscle Car. It is rare – less than a thousand were made – it is incredibly fast, and most of all, it looks the part: menacing, hungry, dangerous. I love it. It was Buick’s last roll of the dice in the muscle car world before that door closed forever, and what a car it was. They certainly went out with a bang. Despite being adored by everyone, it was a little too expensive and didn’t sell as well as it should have. Too bad.
What a car! With a 7.5-liter – 455 cubic inches – V8 under the hood, producing from 350 to 360 horsepower (depending on whether you got the Stage 1 or not) performance was absolutely spectacular, with a top speed of 145 miles per hour and a 0-60 time of 6.2 seconds. The engine was paired with a four-speed manual transmission with floor shift, and all the visual trimmings you could want.
The Buick GS 455 and the GSX were serious machines for a time that was a little less than serious. Reality soon caught up, in the form of hated catalytic converters, reduced compression ratios and concerns about fuel consumption. By 1972, the GSX was already a pale shadow of its former, glorious self, and by 1973, it was …gone.
