Not sure if it was an error on the person parking the Jaguar in the PC aisle or an error on the check out clerk.
I rent at LAX Hertz often, in fact was just there this week, I picked up my PC car at LAX hertz Monday morning April 15th around 10am, and the selection of cars in the PC aisle was impressive. There were 3-4 Infiniti's, a mustang convertible, couple of Camaro convertibles, bunch of 300's, a Caddy and 1 Jaguar XF. I driven the XF before and wasn't impressed by it, either was the Infiniti's, so I took the Camaro convertible, great car.
In the past, I have seen the Jaguar XF parked in the LAX PC section before, good thing I never took it out, as I don't like to do the drive of shame back to the lot.
