I've had a totally different experience than everyone else it seems. I rent cars weekly, some times a couple each week depending on my work travels. Being a preferred member might have something to do with it, but my car is always ready and available when I arrive. Almost every time I have been upgraded! I definitely encourage anyone to join their "club:" and get a wizard number this will allow you to have a car waiting for you when you arrive= no more lines!! As a business traveler who spends WAY to much time in airports and such, its nice to get to the rental car center and be able just to walk directly to my car! I've never used their navigation system so I can't vouch for that, but in my opinion they are much MUCH quicker than some of the other "prise" alternatives available!
