Check around the various Nissan dealers. Once you register with trucare or one of those services like aaa to find the car prices you will have dealers calling you. I am in Richmond and it was between a few dealers here. One offered free oil changes, one added 1500 to any car price I saw for the out the door price and a third didnt sell a new car for less than 13 and used less than 15 grand.
I was a credit union member and although they had negotiated deals, the prices were incorrect as all dealers added to those prices.
Carmax might be another avenue to check.
If price is the main issue I use the kbb website and search 100 mile area.
