The Deville I rented at LGA last weekend had heated front and rear seats and ventilated front seats, which are very nice unless it's really cold out ... and the car definitely drives better than a Town Car. My car also had XM, but it wasn't activated (I've read here of XM on some Hertz cars being activated ... but it doesn't matter too much since I carry my own portable XM for rental cars) and OnStar, but I didn't try the OnStar, but I'm guessing it probably was not activated, but who knows.

While walking around Manhattan last weekend I also saw a brand new Caddy STS that was a Hertz car (the Neverlost kind of gives it away).
