While not necessarily the nadir of the make, the Silver Anniversary Corvette was more a boulevarder than a sports car. Today's Nice Price or Crack Pipe '78 however, is a hard-core-vette.
We've already established that late ‘70s - early ‘80s GM cars suck sweaty goat balls, and the only way to un suck them is through some sort of otherworldly transformation only made possible by speaking the incantation - bring me my cherry picker. Yesterday's 1980 Pontiac Sunbird was one such recipient of this Cinderella-like transmutation, and its hard-ass V6 topped by a prehistoric snail turned the car from mild to wild with little more than a Sawzall to the hood. The collective commentariat apparently love a good magic show and rewarded the beast of bird-en with a 78% Nice Price win. America, intercourse in the affirmative!
