Buick GNX
The story of this model is an interesting one. Back in 1982, Buick started experimenting with turbocharging its line of standard V6 engines. The results were satisfying, so the Buick engineers got permission to develop a performance version that would deliver better acceleration figures.
But in 1987 came the ultimate version they called the GNX or Grand National Experimental. It featured the same 3.8-liter turbocharged V6, but delivered 275 HP, resulting in a 0 to 60 mph acceleration time of just 4.7 seconds. Unfortunately, the Buick GNX was a one-year-only model, so they made just 547 of them. Today, people praise those cars just as much as they did in the late ’80s.
