Opening up the auction to private individuals doesn't bring more buyers, as the brokers are just middlemen -- all the cars they buy get passed on to end customers in a matter of weeks. It may bring more money, if people are willing to pay more to disintermediate the brokers. However, this adds a lot of headache and risk for the auction operator - tons of uneducated customers who won't be able to pay, try to back out of bids, get pissed when the car has defects (auctions are typically as-is affairs), crowd the lot, etc. However - if you see a car you want coming up, try asking a local broker to buy it for you for a flat fee, a few hundred bucks over the closing price. It's a guaranteed sale for them with no hassle ...
