I bought a car in the summer using Car and Classic and sold another on the same site (neither were NSX). On the sale side I had 10 bidders not one viewed the car, the winning bidder a private buyer had the car collected by a courier after paying in full, he had no complaints with the car. The car I bought had 14 bidders, it turned out I was the only person to view. My experience with CandC is they do their best to represent the car honestly with lots of good photographs and specific reference to any problems. But I would still never buy without viewing.
