This Dollar was easy to find in the airport since their line had about 15 people waiting in it while the other lines had 1 or 2 customers. The line took over an hour even though I was Dollar Express (apparently doesn't matter here). After trying to upsell insurance, I was sent to my car. The first car I chose had a low fuel light on so I parked it and grabbed another "mid-size" (by the way, a Nissan Sentra is not "similar to a Dodge Charger" even though I was promised similar to a Charger).
This car had a bit over 3/4 of a tank and the attendant noted it and said it was fine and to return it with the same amount of fuel. The car was beat up but ran fine and I had no issues returning the vehicle.
Two weeks later I get a charge for the missing fuel. I am on hold with their customer service as I write this (so far for 30 minutes).
Dollar overall has subpar service and vehicles but that is what I expect when you go with the cheapest but this experience has been terrible.
