42. Lotus Omega/Omega Carlton
This menacing sedan is virtually unknown in the U.S. Lotus introduced it in 1990 and discontinued it just two years later in 1992. The Omega Lotus was Opel’s rear-wheel-drive luxury model. Lotus tuned it, adding a turbocharger to the powerful stock six-cylinder engine. The 3.6-liter six delivered 377 HP, massive by the standards of the day. It had a 0-to-60 mph time of just 5.2 seconds. The top speed was a record-breaking 177 mph. Lotus installed a body kit, spoiler, and special details in England.

The car came in just one color, a dark green hue called “Imperial Green.” Unfortunately, production numbers were low. Consumers considered Opel and Vauxhall to be economy car manufacturers. The problem was that the Omega Lotus and Lotus Carlton were expensive cars costing close to a fully-optioned Jaguar XJ. Also, the recession of the early ’90s hit the market hard. In the end, Opel and Lotus made only 950 cars. They are valuable classics today and their prices are slowly rising.
