 They really put these cars through a battery of rigorous tests, but they don't even go to the mechanics until the Carfax vehicle history report's been seen and is clean. Then and only then do the mechanics look at 84 points under the hood to make sure the car still runs at factory specs. The body shop gets it. It's reconditioned there, prepped for showroom display, given a price, and then you can come and take a look at it or test drive. These cars all come with a Nissan certified select warranty.
