That does not surprise me, unfortunately.
A few years ago, I rented with Hertz's airport shuttle rate. When I got to the Manhattan neighborhood store, I couldn't help but be curious about something. In the suburbs, the rates are usually in the $35/day range, lest customers get scared away into using their own cars. The rentals tend to be high mileage and beat up. In Manhattan, special one-way plans not withstanding, the rates can be upwards of $150/day. It would be logical to assume that if you pay so much more, you would get a lot more, right?
Wrong. Most of the cars I saw in the Manhattan Hertz garage looked identical to, and just as worn as, the cars filling the strip mall and gas station locations near me.
