I just found out that AVIS and Budget are part of the same company. AVIS seems to have a high rating in the U.S., and clearly has more users compared to other companies. Their service attitude is good, and their response is fast. The elderly gentleman handling paperwork was very considerate! Overall, it feels way better than SIXT.

The waiting time in line was a bit long. I had reserved a 7-seat Grand Cherokee L but was given an S model instead. I specifically confirmed with the counter staff that I needed the larger model, but upon reaching the parking lot, I found out the car was smaller. Unfortunately, I couldn't go back to the counter to request a replacement because the line was too long again. With 6 people seated, the entire journey felt a bit uncomfortable.

Good counter service but vehicle not where it was supposed to be and when found it needed refuelling which was disappointing as we wanted to get away whilst still light. Overall delay about 20 minutes but staff were helpful throughout.

Easy to book and price drop kicked in to reduce the overall cost. Website is easy to use.

Car was as promised and suited our needs.

We booked the rental for Boston while in Scotland. The rental process was quick and trouble free. Plus it was cheaper than if we had rented from a US website.
