I have found a place that is able to mount a track/rack on the top of the Vista roof. It can either be a Yakima or a Thule system. I have attached some pics of my 2009 model. They are called RackNRoad and have 8 stores on the west coast. They have the type of knowledge that I was looking for. Phillip in the Sacramento, CA store is the one who installed mine and I am very satisfied with the rack.
