Again, don't get me wrong, it's not like I don't think the GT-R is a masterwork, especially from a performance standpoint -- but $90,000 isn't exactly chicken scratch either; so playing the whole 'bang for the buck' card really doesn't hold a lot of water with me. It's still far beyond the reach of most people -- and at that level, many (not all) are after a little bit of class too.
A pair of Asics will likely be more comfortable and certainly perform better than fine, hand-crafted Italian loafers. A Timex digital probably handles impact and shock better than a Rolex. But there's a time and place for everything and a lot of wealthy folks could use a little more taste and class.
What good is having the best performance if you're never going to put the car in a competitive, track setting?
