My buddy has an 05 GT and he bought the 6 year 75,000 ESP warranty. We were talking today and he said he might cancel the ESP b/c he's modded his GT so much that Ford would probably just reject the claim. I'm not sure if the dealer figured the return wrong or what but when he asked how much his refund would be he was told 95 cents LOL. So much for paying 1500 dollars for an ESP and basically not using it (since the factory warranty is still has about 5,000 miles left on it).
