Im preferred plus and I reserved a BMW x5 at a local neighborhood Avis using my corp code for the weekend in 2 weeks since I don't feel like going to the airport to pickup/dropoff. It was also significantly cheaper to book at my local Avis.
I only want a BMW x5 and would only settle for a gl450 Mercedes (doubt ID get that). Other then that, such as a infinity qx70, I don't want. When the day arrives to pick up and it is indeed not what I wanted.... Would I be able to cancel even if i have to complain and not get charged a fee? Or would they be able to send me to a Avis airport location to swap it out to what I want and still be able to return to my local Avis fee-free? Any expierences?
