We rented a car at Enterprise Phoenix Sky Harbor Airport. The Customer Service Agents there were phenomenal! The agent checking us in was friendly - didn't oversell but did ask about our needs and offered a reasonable priced upgrade which we took! When we chose our car, the agent was clear, everything was clearly outlined and explained. When we turned the car in, the agents were very friendly and didn't rush us. Honestly, I rent cars often and I think this was the best rental car experience I've had.
