The service from the Americans was fine, but the waiting time for the car was a bit long. The car model specified in the app doesn't really match the one you get at the store. The store assigns cars based on their class, not the model. So, I booked a Chrysler 300C but ended up with a Premium Car category, with three or four options but not the model I wanted. I eventually got a Mustang. The app didn't provide the car I wanted, which is frustrating!
