Pontiac Can Am
Back in the late 1970s, the American performance car segment was just a pale shadow of its former glory. But in 1977, Pontiac introduced the Can Am, a one-year-only model that was the last actual muscle car with big block power and as much power it could produce packed in a unique body style and white color (via Auto Evolution).
Under the hood scoop from the Firebird Trans Am, there was a hefty 455 engine with 200 HP, more than any other muscle car on the market at the moment. The Can Am package consisted of unique rear window louvers, a rear spoiler, and a long list of special optional extras. The car was introduced early in 1977, and the market responded very well. Pontiac received between 5,000 and 10,000 reservations, but only sold 1377 examples in the end.
