Always think about enterprise rent-a-car like a second tier (or third?) operations. My experience at this location was not different.
First, I don't like the policy of "fill the gas to the level it was". Now you rent a car and have no real experience with gas level indicator. You get it from them at say 5/8 of a tank. You are about to return it when your level is 3/8. How much should you put to bring to 5/8? You have to fill it by small shot doing trial and errors until you are at the right level? You fill it too low and hit you with a penalty? You put too much in and you loose the extra money you've put? I like the policy of take it full/bring it full much better, easier to execute for the client!
Also, the first car we got had an engine/transmission issue that made it annoying to drive, we had to bring it back to change it. To their credit, the service was nice and they did pick us up and drop us off and they made to fuzz about changing the car, yet this is the kind of issues that I had too many times with enterprise.
