My wife currently drives a 2000 Mountaineer (5.0). We are in the market for another vehicle and among our short list so far are a '07-09' Explorer/Mountaineer. I did some looking on the forums and didn't really come across much, but I'm wondering if there are any issues to be aware of on these newer vehicles? Any big ticket items that tend to go bad, or other sure fire repairs (other than normal wear and tear) that would be in the future? I'm also under the impression that there may be little, if any, difference in mpg with a V6 vs a V8?
