Am I the only one that doesn't understand why cars like this get so much attention.  If  I were able to afford a car like an R8, I would rather put my money and time into building my own car.  To me there is much more satisfaction in chasing down the Germans and Italians in a homebuilt track car than worrying about putting your $100k sportscar into the weeds.
I also happen to like the looks that I get when driving around town with a roll cage, big brakes, open exhaust.  Something about a Taurus passing a Porsche just gets me all tingly inside.  Same goes for the guys that bring e30's, Mustangs, Mazdas, etc. to the track.  Pretty much anything will get around a track well enough with a good set of tires and a decent driver.
Then again, I wouldn't mind having a Morgan for a nice sunday drive. lol.  I'm sure there are reasons that people like "mass produced" supercars.  It's just not obvious to me.  
*I say mass produced not in the literal sense, but as a production comparison between a team in a factory versus me in my garage with a welder.  I can engineer to my own tastes and not based on what the public wants to see.
