I had a one day rental from the Nashville location right around the street from the airport at a B class rate, expecting a C class upgrade and was given a Q4 upgrade as I assume they wanted other vehicles in the C class fleet available for multi-day renters. I was also picked up, even though the location does not normally do pick-ups.
Amazingly, that location also had a one-star review on Google, but I did my part to help them out by giving them five stars.
