10. Buick Wildcat GS
They introduced the Wildcat in 1962 as was one of the first personal luxury coupes. It featured a performance-tuned engine and other go-fast options. And since it was a Buick product, they guaranteed the luxury appointments and upscale options. Even before the Rivera GS or the muscle car craze, Buick noticed there was a big market for a full-size coupe with the performance of a sports car.
Young and successful people wanted an upscale product that looked expensive, but still had enough power and driving dynamics to make every day driving fun. In those days, luxury coupes like Thunderbirds or Eldorados were all large, heavy cruisers with soft handling. So, that is why Buick introduced the Wildcat. Available as a regular four-door hardtop, two-door coupe or a convertible, the Wildcat was a separate model.
Under the hood was a powerful V8 from the top of Buick’s engine lineup. However, the success of the Skylark GS and the Riviera GS inspired Buick to offer the GS package on the Wildcat, too, but just for 1966. However, the package was much more than just two letters on the trunk lid. It consisted of a Riviera 430 V8 engine with 340 HP and a chrome air cleaner.
They added a revised suspension and brakes, and even Posi-traction limited-slip differential. This made the performance even better than the regular Wildcat. And lastly, the GS package was available for both the coupe and the convertible.
