Here is one that I used. There are so many to use from, and your choice may differ, but it fit the 06 very well. I could tie it underneath and then I also had the tarp clips in front and back to keep that part down and attached in the winds. Did a pretty good job, especially when I was away for a time. If nothing else, keeping the UV, birds and all the little seeds from sticking to the paint is worth the investment when it sits outside and you don't have time to wash it or wipe it down.
I never seemed to have a problem with any scratching and it was nice to uncover and after a quick wash, the paint was still good to go and with a quick detailer spray she was shining.
