See if you can find a car broker when you figure out what you want. Tell them what it is you are looking for (model, mileage, year, color, options, price range) and be patient. They will check all the auctions and such and see what they can get for you.
My buddy flies a lot for work and sat next to a broker on a plane one day about 10 years ago. They still see each other on flights sometimes and my buddy used him to get their Avalon (that was about 9 years ago) and they have him looking for an Expedition right now. They are very picky on their options, so it's not an overnight thing but if he finds what they want, they will actually save quite a bit as he charges a fixed fee over the auction price and a fee to move the car from the dealership he works out of and your home and that's it.
