The first is a 97 4.6 2v 5spd 4x4 123K for $1100, the second is a 2002 5.4 2V auto 4x4 278K for $1000
The first has possibly a timing chain issue(No cam phasers in this engine), the second has a blown out plug. Daughter needs a vehicle soon, she has a horse and wants to be able to pull a horse trailer, and she has been working and saving her money, so one of these will be hers.
