Beware of extended warranty's other than Ford. About 4 years ago, my wife's sister bought a used Ford Five Hundred, took an extended warranty through the Ford dealeership she bought the car at, that was not a Ford one, some other company. When the throttle body went, this was not covered, cost her $1,300 for the repair, then a few months later, another repair was not covered, so another $900. These repairs would have been covered under Fords ESP warranty. Original warranty was $1,400, plus the 2 repairs came to $3,600 out the window !
