While you're in Montrose, check out Last Dollar Road that's just outside of Ridgway and takes you over to Telluride. It's a pretty easy trail that has some great scenery. I'd skip it if it's raining as the mud can get pretty slick.
I have a sun roof and the best thing I did was have it tinted with the ceramic film for heat/UV protection. It really made a world of difference here in Colorado. On a sunny day I no longer need to close the shade to be comfortable while driving.
