Seems like the day for ST220 threads, from what I understand and been told by mechanics at Ford, is some things you can do yourself, spark plugs require some serious effort, for some reason that sticks in my head. Oil changes are straightforward, but you need to take the car's floor pan cover off, which has about 20 retaining clips so you'd probably need some help (and axle stands) for that.
I think it's more pain than it's worth for how relatively cheap Ford servicing is. I'm sure they are doing some "Value" servicing now, but I'm not convinced it's through enough.
edit: plus no stamps in the book, which will make private buyers walk and dealers you part-ex it with try to take you for a ride. But if you intend to run it into the ground it's probably worth doing yourself.
The service sheets are available on the Ford wiki.
