Are you a USAA Car Dealership? I am a member and I can get a discount if I buy from a USAA dealer.

They don't recognize it from my interactions with them. Reach out to USAA directly for confirmation.

I don't believe so. I mentioned USAA when I was car shopping there and got a blank look. Your best bet is to call USAA with what you're looking for. They have a procurement service. https://mobile.usaa.com/inet/wc/car-buying-services-products
