The local CarMax may have auctions for the local "Mom & Pop" dealers - you won't be able to bid, but if you talked to a registered bidder ahead of time and told them what you are willing to pay (in cash) for a Leaf that day, they may bid on one for you. Point out that they won't have any lot insurance fees on it, since you'll be taking delivery immediately.
Yes that works pretty well. My wife wanted a specific model of used car several years ago so we told our regular mechanic (who has a dealer license) to find one in good condition at the local auction and bid up to a certain price. It was worth paying him for his time to attend the auction and filter out the cars with problems.
