I'm glad I found this forum because I was wondering the same thing about hertz fleet. I rented a Mercedes from them last year.
I have a question myself, I plan on renting a SUV from hertz when my friend comes to visit and he lands at laguardia so I will rent from that location. getting to my question when I get there and I see what SUV's are on the lot can I ask them for that specific vehicle because I really don't want to get stuck with the xterra.
