Sadly you can't buy it in the US.
This is not a car you buy when all you want is a sports car. The Lotus Exige V6 Cup is a barely street-legal full-on track car. God knows how Lotus got this thing approved for road use, and unless you know how to handle a car of this caliber, it’s best to get something else. With a supercharged V6 engine producing 345 horsepower and 290 lb-ft of torque on hand, the Exige V6 Cup is all about one thing: speed.
As you might expect, this Lotus isn’t the most comfortable thing to drive on the road. A hardcore sports coupe never is. Sports car purity does have its drawbacks…as well as its countless perks.
