I would too. I've gone with this party warranties with all of the used cars that I bought over the years. I am very picky in the type and condition when I buy used car but you cannot tell years down the road that anything won't fail. Ford or any other manufacture quality aside, I wouldn't have bought it if I didn't think they were good - they're all man made and may have flaws/failures. I can tell you from past experiences short of a BMW CPO warranty, I've had best service thru the top tier Endurance warranty. CarMax also has good warranties. I think paid approx 3800 for 7yr/120k miles on our current 2018 Max Limited. Had similar plans on our previous 2012 Touareg TDI and 2018 Volvo XC90 T8 Inscription. On our current expy, we would've had to pay 2250 for AC condenser just 11 months after we got the warranty.
That said, I will say AVOID any warranty that issues you a contract with American Auto Shield or Car Sheild. Do your homework and find out who will service/administrator because companies like CarChex will sell you the warranty and then pass it on to another like American Auto Shield. They will either not approve repairs, ask you to authorize diagnosis and only pay for parts of the service when they finally find underlying problem, or cover the repair but at lower than market price leaving you to pay for difference, in addition to the agreed deductible. Ask me how I know...
Issues with things not covered under warranty were either due to the unlucky pick of the wrong company or not getting the highest all-inclusive plan
