the cost was too much, and it would not let me book the 5 days I wanted without high cost.

The pick-up and drop-off process was very efficient, and they even upgraded us to an SUV, which was a pleasant surprise.

Convenient and fast, with simple procedures.

Very good

Hertz were very poor at pickup. Delivered a different car then was on the booking. Kept trying to sell me additional insurance, upgrade to car and winter tyres (not necessary for the highway driving we were doing in Calgary). The car did not have a full tank of petrol. We discovered a crack in the windshield within 2km of leaving the airport and Hertz tried to say it was our fault. We returned to the rental location and received the car we originally booked which was not offered when we first arrived. On the contrary, the dropoff process was very quick and smooth and the staff was friendly

Like: We were offered an upgrade to a 2018 Volstwagon Passat which had more leg room and trunk space than the booked car. We were very happy with the fuel efficiency, how the car drove and quality of the vehicle.
Dislike: We were under the assumption that Hertz would fill the tank for us at their discounted rate, however didn't know that they would charge us for a full tank regardless of how much fuel was in there.
