Google it. I live in Florida and an extended warranty is considered insurance, which is regulated by the state. My problem was, I bought a 2006 F-150 XLT with 65000 miles and the dealer wanted $3000 for the ESP(2year with $100 ded.). I thought I could get it cheaper, but I learned since it was regulated by the state, it was the same everywhere in the state. Luckily for me I bought one at a Ford dealership out of state (Warrick Ford) I got the 3 year Premium Care with $50 Deductible for $1800, but I had to use a out of state address to purchase although they mailed it to me in Florida. They just needed a address to make it legal for me to purchase in Florida. Ive had it in twice so far - Alternator and window switch and they didnt even charge me my deductible.
Believe me, I spent alot of time researching extended warranties and only felt safe with a Ford backed warranty. There are alot of horror stories about extended warranty places that deny coverage for what you would think covered. They can blame anything on wear and tear and deny. Like everything else in life you get what you pay for.
I bought it becasue my wife had a Focus station wagon when they first came out. right after the warranty expired, the AC went. Took it to a AC only repair shop, spent $1200 to get it replaced, was told it came with a 1 year warranty. Jump foward 10 months, the AC went bad again. I took it in and was informed the warranty is good, but I will have to pay $800 labor. That wont happen to me again (I hope)
