You can buy an Extended Service Plan directly from Ford on this vehicle. It does not appear to matter where you got it, just that it qualifies. And basically any Ford-made product that's still under warranty automatically qualifies.
I requested a quote on your potential purchase, using the VIN from a front wheel drive FEH I found listed for sale on the internet. Here's what I got back:
2005 FORD TRUCK ESCAPE HYBRID 4D 2WD
Premium CARE 4y 48k miles, $50 deductible = $870
Extra CARE 4y 48k miles, $50 deductible = $740
Here's a link to their site:

this may take care of the "peace of mind" part of this dilemma for ya!!
* Note: In my area this vehicle is a good buy at $18000-$18500. Your mileage may vary.
