They only mentioned that returning the car without a full tank of fuel would incur charges equivalent to fueling at a gas station, deliberately hiding the fact that there were nearly ten times the fuel price in additional labor fees and other charges! Moreover, the contract had an additional clause stating 'Pre-purchase a tank of fuel upon pickup, allowing the customer to return the car with an empty tank; if the customer refuels before returning, the car rental company will not refund the difference.' This was not mentioned or introduced at the time of pickup! As a result, even though I only used one bar of fuel, the bill included a hefty 60 euros charge! The actual vehicle provided did not match the specifications other than being a seven-seater. I never expected such notorious behavior from the well-known Avis, absolutely negative review!
