The 05 to 07 were the best years imho, but they are getting long in the tooth, and unless you are mechanically inclined with your own tools, you should pass. The late model foci seem to be reliable, collapsing fuel tanks aside, but only with a manual transmission. I never cared for the styling of the 08-11, but they do have a bulletproof 2.0 duratec engine as a big plus.
