Launched in 1967, when GM decided to give Pontiac a piece of the pony car market action by sharing the Camaro’s F-body platform, the Firebird became an integral part of the muscle car wars within a couple of years. 1970 saw the introduction of the second-gen model, which included the most brutal Firebird ever built. In its range-topping trim, the coupe came with a 7.5-liter V-8 under its hood and more than 360 horsepower routed to the pavement. With Pontiac out of the automotive scene for more than four years as of October 2014, the Firebird is one nameplate we wish was still around. Fortunately, the legacy of the early cars grew stronger the past four decades, and first- and second-gen Firebirds have become sought-after collectibles.
