so it sounds like just being on the sponsors list in of itself doesn't mean much of anything regarding the company's trustworthiness, as they are not actually vetted or verified to be honest/reliable before being put on the list...one can use the list as a starting point to get company names, but you will still need to research each company to decide for yourself if you feel they are trustworthy....that was my initial assumption, and that's how i personally used it in my search

No, I don't think this BB does any sort of vetting. BUT, the fact that so many people here said that Kenny's was so good is what got us to switch. So many TTOLers can't be wrong. And they were not. Kenny's is the best.
We have used AAA and they were good but you have to get in a bus and get to the rental agency. Lesley brings the car to me. and I LOVE that.
