Just got back from the Las Vegas Auction. I have been to it the last 3 years. Bought my CBX there 2 years ago. There are more British bikes than anything, but the Japanese bikes seem to do very well there and that segment of the market is getting stronger right now. Last year there was a K0 750 that was really junked up and fetched $5750. People tend to over pay, it's a better place to sell than buy IMHO, but sometimes a deal can be had, I only paid $3500 for my CBX, but it wasn't running at the time and probably was a fair price for it.
