I admit that I am not your target market, since the only vintage Campagnolo I have ever owned came on a barn find I parted out last year... but as much as I hate to admit it, since I am turned off by the used car salesman type of hype from the other listing you referenced, they do seem to bring in higher bids.

Think marketing! What is the old saying? I think it is: You don't sell the steak, sell the sizzle!
