Paid in full, but couldn't pick up the car at the store as it was rented to someone else.

Very satisfied.

Returning the car was very convenient.

Excess human involvement. The process could be significantly more electronic or simplified. They had to shuffle through keys thrown in a draw for 5-10 minutes before discovering they didn't have the car model ordered so they provided a suitable but very different alternative.

The experience of renting through a rental broker and not directly from a rental company was a little uncomfortable at first (is this transaction legitimate/am I getting ripped off) but in the end the cost saving was worth the third party being involved in the process.

Good

Easy to book
