18. 1973-1991 Chevrolet Suburban
In 1973, Chevrolet unveiled the next generation of their popular Suburban “carryall” truck. The Suburban would go all but unchanged until 1991, with Chevrolet opting only for subtle performance upgrades and minor facelifts. The 1973 Suburban also showcased changing design philosophies as Chevrolet eschewed rounded corners and round headlights for squares and sharp angles. Available with a 454 7.4 liter V8 engine, the Chevy Suburban had plenty of power, although like most trucks, felt the bite of the 1970s oil crisis.
