If it's the same James I'm thinking of, he is a younger guy (under 30) who used to live in Atlanta, and recently moved down to the southern Florida (Delray Beach/Boynton Beach) area.
His was the first website I found for NSX's back when I first started looking, and I've talked with him over the phone on several occasions after e-mailing him and asking some NSX questions. He is very nice, and helped me in my decision to buy an NSX. I believe he's also owned a Viper GTS and several other exotic cars.
Last I heard, he owned a black 996 Coupe, but was trying to sell it to buy a Ferrari 355.
