if you can find out from the person/dealer you bought it from if the 30K and 60K maintenance was done on it i would do that first. Why? because ford transmissions suck and if you flush it durring the 90 or 100K and it never was before theres a real good chance youve just fuccked yourself....saddly im speaking from experience, dont take it to ford because most WILL fucck you. since you just baught it chang the oil, spark pluggs, and maybe wires too especially if their still the stock ones. make sure all fluid levels are topped off and possably have a local mech take it for a drive, some if not most will do a "free" road test for you. as for those gehy headlights E-bay my boy you can't beat those prices as many sites will sell the same kits on e-bay for up to 10 to 20% cheaper in hopes that bidding will increase it
