1968-1975 Chevrolet Blazer K5

The Blazer K5 was built to compete with similar vehicles like the Ford Bronco and International Scout. And while those trucks are also cool, we like the Chevy's wider and more menacing stance. Though the Blazer was produced with a removable fiberglass top until the mid-1990s, the early '68–'75 versions, where the whole roof comes off, not just the section behind the driver, are the ones you want. A convertible four-wheel-drive pickup with usable rear seats and an 8-track player? This might just become your only car.
