15. Buick Reatta
It seems like everybody forgot about the sleek Buick Reatta. Introduced in the late ’80s, the Reatta was Buick’s halo car, and it was a cool-looking two-seater coupe or convertible built on shortened GM’s E platform.
Under the hood was a 3.8-liter V6 with independent suspension and disc brakes all around. All Reattas were highly-optioned cars, and despite dating from the late ’80s, they featured board computers and lots of pretty modern electronic systems. The production lasted four years, and over 21,000 were made. Even though the Reatta was a composed and well-executed car, it was considered a flop.
