Before buying a new Ford consider this.

I work on cars under ford warranties, and aftermarket warranties and both will find any way to duck out of paying. Aftermarket warranties can sometimes be absolutely useless. I'm currently replacing a cylinder head on a 4.0L explorer (OHV) that was cracked between the valves on the #3 cylinder (very common problem). Their aftermarket warranty denied the claim because it was not an "internally lubricated component". So basically that 2-3,000 dollar warranty was absolutely a waste of money. I wouldn't ever consider modifying a new car unless i was willing to pay for repairs out of pocket because of the risk involved, this goes with any manufacturer out there.
