I would only get the FDII if you are doing some serious off roading. It makes the compass/patriot very capable off road, but at a pretty big MPG disadvantage. if you need a solid all weather vehicle, the FDI (or just standard 4x4 is fine) The FDII still has the cvt, while the 6 speed is the auto on the FDI. There is nothing wrong with the cvt, its a reliable smooth transmission. the problem lies with people 1) hating new things, and 2) refusing to get used to the cvt, as it does take a different driving style than a typical auto, but one that can be picked up in a few days of driving.
Check out my youtube channel in my sig for videos of what I consider to be serious off roading.
