I bought a 7 year/100,000 mile warranty with $100 deductible last year from Flood Ford. Well, I decided to extend that to 8 years/100,000 mile with $200 deductible. Flood Ford was okay with that and only charged me a bit more than the difference ($125). That's pretty good service. Of course, they haven't sent me the new contract yet but they've charged my card and said the contract will be sent tomorrow? Haha. I'll report back if I get screwed.
Also, see the following from Ford Flood's website:
