Nothing I would be concerned with other than a clean carfax if you can get one. I just sold my 04 F150 heritage truck which had the 4.6 2v and automatic, it had 371k on the clock and it did not drip a drop of fluids whatsoever. Engine and transmission were original, including the water pump and fuel pump and starter. No spark plug issues. It didn't smoke at all or miss. It ran like a top, the transmission shifted like new. I did have the transmission powerflushed every 100k miles which may have contributed to its life, I maintained the engine as well and, well, there you have it.......371k and ran like a champ when I sold it! I think you will be fine. On another note, the 02 GT I sold to a friend a few yrs ago which just turned 100k on the clock recently had a plug blow out, they "heli-coiled" the hole and it was back in business, However, that car had 4:56 gears with an auto transmission, so it does see a little abuse.
02 yellow GT auto......SOLD.
Looking for another, stay tuned!
