IMPORTANT UNDERSTANDING REGARDING GO RENTALS BELOW... But first, I had a terrific experience with GR -- which I relate below. The important understanding I can provide is that Go Rentals specializes in private aviation. They are generally located at suburban airports where private planes (all the way from a small Cessna up to a larger private jet) come and go frequently. If you compare GR to Hertz, Enterprise, we're talking apples and oranges. You won't get cut-rate pricing from GR, like you might get from typical retail organizations. My experience was nothing short of first-class. I was picked up at Phoenix Sky Harbor by a GR representative, brought to their off-site location and delivered the car there personally. I was able to drop the car at Scottsdale where my airplane was waiting for me a couple of days later. (I fly a Turboprop Piper Meridian and it was delivered to Scottsdale after its annual inspection by the aviation shop. I then flew it home to CA after my annual recurrent training in a Meridian simulator.) I also used GR in Napa where they brought the car plane-side and we were able to load our luggage straight from the plane to the car. Hope this helps everyone who reads it... They may not be for you if you don't need private service at an outlying airport.
