I have seen various threads on this topic. It seems that a lot of people really like the Trailex enclosed standard trailer. Some have ordered an additional 6" in height. I also like this trailer as I would use my Cayenne to tow my GT. But my question is this...if you are really planning on using the trailer only to tow the car to various tracks and venues within a 300 mile radius, 5-6X/year, why not use an open trailer and outside custom-fit car cover (tied down of course)? Considering how often I will trailer the GT, 17K for the Trailex trailer seems like a lot when I could buy an open trailer for 5-6K?? Some tracks like VIR have garages for rent which I use when I visit them. Curious what various opinions on this topic are?? Is an open trailer just not really an option for the GT?
