It's just okay. Avis and Budget seem pretty much the same, always using tricks to make you spend more on their extra insurance or options like returning an empty fuel tank. Even if you decline, they may sneak it in while you're not paying attention. They'll claim the agreement was emailed to you in digital form. Make sure to demand a paper copy after signing electronically and double-check it immediately!

I booked cars three times during this trip, all with AVIS. It felt great, so I kept using them.

The service was very enthusiastic, they offered an upgrade recommendation but did not impose it aggressively.
