21. 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.
20. Alfa Romeo GTV6
The GTV6 is highly recommended. The Tipo 105’s successor was the coupe version of the Alfetta introduced in the late ’70s. It had advanced construction and suspension and featured several interesting details. It had a transaxle gearbox which vastly improved weight distribution and handling. Second, it had De Dion type rear axle which helped cornering.
With a 2.5-liter V6 engine in the front, the GTV6 delivered 160-170 HP and good performance by the standards of the day. Even today, GTV6 is known for its perfect driving dynamics, solid acceleration, and a soundtrack from the high-revving V6. Interestingly, this car was sold in the USA, even with an optional turbo kit by Callaway performance good for a whopping 233 HP.
