I ended up paying a garage to get the car started as the process with Avis failed badly.

Very satisfied

Smooth pickup and drop-off

Satisfactory

The reception staff were very friendly, but not very familiar with the QEEQ rental voucher. Due to a flight change, we arrived an hour earlier than our scheduled pick-up time, and the quoted price was significantly higher than our reservation price. After we pointed this out, they explained it was because we arrived early, and then they corrected it. During this trip to the US and Canada, we rented cars three times, and twice with AVIS, arriving slightly earlier than the reservation each time, and encountered the same situation. The US is a trust-based society. For both pick-up and drop-off, no one checks the car condition, which takes some getting used to, but this mutual trust feels great.
