Excellent

Like: I rented cars from Europcar in both Melbourne and Brisbane, and their vehicles were in good condition.
Dislike: For Europcar, they could consider providing a summary of information about the nearest petrol stations to Europcar car return locations. It would provide drivers an ease of mind when returning the vehicles in full petrol tank. In addition, Europcar could consider pasting a decal on the windscreen that provide information on the type of petrol (RON91,95,98) to refill, as well as helpline contact number (24 hours) to call in case of emergency. As for EasyRentCars, maybe you could consider having a points reward system so that customers will always use your system and services. It could be free upgrade of vehicle, extra days drive, waiver of baby seat fees etc. If possible, it would be great to tie up with other online platform such as Hotel.com or booking.com, so that if we book a vehicle through them or hotel through EasyRentCars, customers could enjoy better rates. Just some feedbacks to stay ahead of competitions.
