I'd love to own a classic late '80's, early '90's Porsche 911, for the very same reasons that you point out, not because I feel some crazy need or desire to do 180 MPH on public roads. Can you imagine all the squids there would be flying down highways and freeways in Porsches, Ferraris, and other exotic sports cars if it weren't for the fact that the majority can't afford to buy one? That those cars are so expensive is a good thing in my opinion.I find it more refreshing when someone proudly posts up their new 600 or 1000 and they say they bought it because they've always wanted one since they were a kid/gives them a boner/can afford it/ have always loved them/ waited for ages to find the right one etc.
Instead of those trying to Justify that they needed its performance.
As far as 600 super sport and 1000 sport bikes go, we have two problems with them in the U.S... one, they are relatively cheap to buy (especially as used bikes), and two, we have no tiered licensing system to keep those bikes out of the hands of inexperienced riders. It's unfortunate.
