i never bought an extended warranty - but my local dealer ONLY sells third party warranties from "Fidelity"..... before I bought the car it had an extended warranty that went up to 75k miles from "Fidelity" and they paid out ON EVERY CLAIM while my dad owned the car. RMS repair, new cats, new top, new dash...they paid more than the warranty cost....
now i'm rolling around w/no warranty hoping that nothign goes boom...
on a side note - if my motor blew, i plan to do a 3.4L swap.
if you HAD a warranty and HAD a failure - will warranty companies work wtih you to apply the $$ to a swap or will they say "fix it back to stock or we won't pay"...???? so if you WANTED to do a swap you would have no way to do it?
