Very convenient. There is a shuttle at the airport. No promotional pitches when picking up the car. Clear signage for returns. The return process was quick and smooth without any issues. Everything was perfect.

Thrift gave us a free upgrade to a mid-size SUV. It was very appreciated when it started snowing in Denver

Like: Costs, promptness
Dislike: All of the rental cars in the fleet (Intermediate) were pretty badly scratched up and dinged but there was no inspection of the car before we left. We had to point that out to the security person at the gate before we went the lot, to make sure that we wouldn't be blamed later.

Like: The rental agents were all friendly, helpful, and the price for our rental was excellent.
Dislike: The car was just ok. I had never driven a Nissan Sentra and was disappointed with the performance. I picked the car, so that is on me. The interior of the car was not very clean.

Like: Used Thrifty cars. Had no issues in communication. They were ready for me when I showed up and all my information was already input.
