James, perhaps I could offer a little advice. I'm a used car dealer in upstate NY. Here's my suggestion. Ask around to friends, family, coworkers regarding a good experience with a local dealer. Don't call, but actually go there and sit down with the boss. Tell him exactly what you want down mileage and a few reasonable colors. Let him know it's a cash deal, no trade. You want a car with a clean history (carfax) and that you have a time period of a few weeks to finalize the deal.
Every dealer gets their inventory from auctions. They all have the ability to search before hand a see what's available for that weeks auction. If you give me a mileage range, I'll give you a reasonable price range based on your area.
