Agree with above posts. We need to define "Super Car." For me, Super Car is different than "Exotic." This is how I categorize cars:
A Super Car in my point of view, is a car that has been made to break all the limits of performance leaving behind luxury, efficiency and practicality. SOME (not all) of these are not even street legal. A good example of these could be the Dodge Viper ACR or the more extreme Viper ACR-X. The Saleen S7, Mostler MT900 and Pagani Zonda R. In very rare cases the practicality has been taken care of, making them more then a fair daily drivers, just like the McLaren F1. But that's a very rare case.
An Exotic could be defined as a car that doesn't compromise anything, and it's all about high end technology and features. These cars might exhibit flamboyant design, rediculous amounts of horsepower, or extremely unefficient engines. In some of these, the high end luxury and comfort features makes them great daily drivers. A good example of this might be the Bugatti Veyron or the Mercedes Benz SL65 AMG. Others might sacrifice a bit of luxury for performance like the Lamborghini Murcielago. And some have evolved thier driveablility thanks to technology, leaving them between the Exotic and Super Car category. Example, the Lamborghini Aventador. Their prize is in most cases far beyond what the car might deliver and it's just based on how rare the car can be like with the Lexus LFA.
There could also be another category which I like to think of as Specialized Sports Cars. These cars are somewhat accessible to the general public(in some cases) asince they can be based from really cheap economy cars as the Honda Civic to luxury sedans as the BMW 5 Series. These make also great daily drivers as most of them are based on regular models, though they might also sacrifice comfort and effeciency for performance. Example: BMW M5, BMW M3, Dodge Viper SRT/10, Corvette ZO6, Lamborghini Gallardo, Ferrari California, Mercedes Benz SL55, Mercedes Benz C63, Lotus Esprit, Honda Civic Type R, Ford Focus RS, Nissan Fairlady Z, Nissan Skyline, Lexus IS-F, Nissan GTR.
Another category would clasify as Purist Sports Cars. These cars do things the wrong way for good reasons. Luxury is not their strength, comfort is not an option, efficiency and durability is not the most important aspect either. Safety is a joke. Their performance is often way below what their numbers might suggest in some cases, and in some they might be faster than one might think though demanding the driver more than he might be able to acheive. But these are probably the most enjoyable sports cars. Examples might be all the TVR models, the Lotus Elise and the old Ruf models.
Note that my method of classifying cars is not very exact and some cars might be stuck between categories.
I STILL bust up laughing when I see that.
