I have an 07 with 66k on it and an 08 with 191k on it, both with the 5.4. The 08 have the timing set, oil pump, etc changed by fordtechmakuloco at 160k. If it's been maintained and has a clean body I wouldn't hesitate to buy another.
Where are you all getting hair cuts at to pay that kind of money? I go to my local barber shop in a small farm town in Indiana, pay $11, and usually give $3 tip. He's always busy, usually have 4-5 people in line ahead of me when I go.
