I used USAA car buying service for my Tundra this summer. My father was military so I have used USAA for my car and home insurance for years. I was looking at a 2010 at a dealership but when feeling them out there would be no wiggle room on the price. They wanted 5k more than I was willing to pay for used. I called USAA and they found me a couple of options new and used. When the salesman emailed me asking if I wanted to see the used one I stated a new one was onky 4k more would they take 35k for their used one he said no so I bought the new one at the negotiated price through USAA. In and out in under 2 hours.
