"The HSC show car is "a realistic proposal" for the next-generation NSX, says Honda President Takeo Fukui."
Did you guys miss that quote from the main page? The "HSC" is simply a concept car moniker. The president of Honda said it is the basis for the "next NSX". Why would anyone think they would bring out a new supercar and *not* leverage the NSX name? That would make no sense at all. It will be the Acura NSX in the US and the Honda NSX in Japan.
There is no way that a Honda dealer can move that car in the US. It's questionable whether or not the *Acura* dealers ever really figured out the NSX, to be honest. The Honda dealers would be an utter disaster (as they are with the S2K).
This isn' a Honda problem really. Dodge dealers suck with the Viper and Chevy dealers are horrible with the Vette. These dealerships want to sell SUVs and mini-vans, not obscenely expensive sports cars. It's almost enough to send you to Porsche.
The Porsche salesmen I've dealt with were all Porsche owners/enthusiasts who knew more than me. One of them was even a club racer. By contrast, at the Acura dealer where I bought the 03 NSX, no one really knew what the hell it was and people lining up for the monthly specials on the xL (RL, CL, TL, bleh) got more respect and attention.
