I signed up for a car rental through my company expense software. They quoted me slightly higher when checking out, and urged me for the insurance, but declined due to company guidelines.
We received the car promptly and they went through a 360 panorama inspection. When returning it, things were simple, and they emailed me my bill (on top of a requested printed copy). Charges when leaving were 40% cheaper which made the whole experience awesome. Friendly people for a small business.
Car limitations involved Arizona, Nevada, California, Oregon and Utah (not like it mattered)
Very pleasant experience, though intimidating at first. $159 for 3 days!
