Always the most expensive!
My Friend and I rent a car from Enterprise years ago in SF, good service!
My husband and I recently (attempted to) rent a car from Enterprise in Ithaca, NY. As I needed to be in Rochester for medical needs, we had reserved a car several days before our trip. We arrived at Enterprise at 8:00 am on the day that we had reserved a rental car for our trip. Several employees were running around frantically as they not only did not have a car for us -- in addition, they did not have a car for the couple in line in front of us! My husband explained to them that this was inexcusable as we had reserved a car for this day/time and they said they were sorry and they didn't know what they could do (they obviously had overbooked their vehicles and didn't want to admit it). As we didn't have much leeway for time, we headed to Avis at the airport where the helpful attendant informed us that they get folks all the time from Enterprise as Enterprise is notorious for overbooking their vehicles. We were extremely happy with Avis as he had us on our way in no time with a super rental car -- and even gave us a discount for our trouble with Enterprise!
