I have a shot at a 2007 f150 lariat, loaded, beauty of a truck, for a killer price, but it is a high miler, @ 250 km. It has been babied and has not towed anything, just a highway high miler. Any feedback is appreciated. What can a guy expect to get km wise, and well maintained. Can these fords go over 400 km without major worries, or am I smokin something?
