There's going to be different variations of what people define as "Best". Whether it be the most luxurious, fastest, moisture-in-the-pants looks, lightest, most comfortable, etc.
I would nominate either the 340R or the 2-11, and even lets say a 2010 Exige S260 (which I'm still awaiting delivery on). It's all about the hammer being dropped down.
If I wanted comfort and luxury in a car, I'd buy a Maybach and hire a driver to haul my lazy rich a$$ around.
Just my $0.02
SIMPLE RECIPE FOR EXCITEMENT: Take 1 new Exige. Throw in a supercharger. Add 6 gears. A dash of 94 Octane. A sprinkle of carbon fiber inside and out. Toss in 1 MadMan. And finally heat tires and pavement to taste. Recipe produces 1 Lotus Exige S-260 and full satisfaction. Hammer Down!!
