Jz-
The G37 was definitely tagged and showed on my receipt as a G...maybe a mistake? To be honest, I think that a G37 is a good premium vehicle and not really prestigious if you ask me - kind of like the Volvo S60, although I know that's a prestige. I actually had a luxury booked and it was a Town Car which I took a pass on so they downgraded the reservation. I Have rented all of the infiniti line of Hertz cars and only have seen one G37 in my travels.
