You should buy a Ford extended warranty if you think the additional peace of mind is worth it. Just be aware that you may never have to use it. Here are a few things to consider.
Coverage: Also known as the Ford Extended Service Plan (ESP), the extended warranty from Ford offers either extended bumper-to-bumper or limited powertrain coverage for a total of up to eight years or 150,000 miles—whichever comes first. Extended bumper-to-bumper coverage is the more expensive option.
Usage: In an ideal world you’ll never have to use your Ford’s warranty, extended or not. And if you do have unexpected repairs, your warranty will only cover them if they can be traced back to a manufacturer’s defect—it will not cover standard wear and tear.
