Wow, the other reviews here are kind of surprising. I've had nothing but great experiences the handful of times I've rented at the Ahwatukee Hertz over the past 5 years. That's before and after I signed up for the free rewards Gold Membership program a few years ago.
I always picked up/dropped off the vehicles in Ahwatukee, so never had to deal with the airport. They have a key night dropbox which has come in handy for me a number of times
The rewards add up fairly quickly, and as a gold member, checking a car out is a breeze. Place the order online, and all they need to see is your DL and your CC to verify, then you're on your way
I believe each car had free Sirius radio. I especially like that every time they were able to honor my requests for a car with a USB connection. One time I even was given a free upgrade because they were out of cars with USB at the level I reserved, which was totally cool of them
Oh, and bonus? It shares the strip mall with the awesome Bagel Man and The Original Burrito Co!
So yeah, check my reviews, I'm a straight shooter. I happily use the Ahwatukee Hertz
