What i found in my research, was some of the cheaper companies use older cars, and have had breakdowns, tire issues with no spare tire and jacks, etc. Also there seemed to be a game of claims you damaged the car and they want compensation. I found no issues with companies like Automax, Kenny's, AAA and some others that where mentioned here. I love a great deal as much as the next guy, but piece of mind swayed me on this deal! Word of mouth is the best advertisement!
