With its unassuming looks, this underrated classic muscle car is a perfect definition of a sleeper. It didn't look like much on the outside, yet it packed the power that made it the second fastest-accelerating production car in the world at the time. What was the name of this beast?

Made in collaboration with McLaren, the Buick GNX (Grand National Experimental) was, indeed, the second-fastest car in the world at the time. With a 0-60 time of only 4.6 seconds, it could only be beaten by the Lamborghini Countach. Only 547 were ever made and each one is a sought-after collectible today.
