If you can find a same-colored Expedition at a junkyard with a good front fender and both doors, it'd be a much easier truck to sell. The rear quarter molding would make that damaged panel look better. As-is your target audience is pretty small and full of low-ballers.
Pacific Green (PS) was a 97/98 color so finding replacements could prove tough. Then factor pinstriped or not, some were solid green, some had silver lowers, some had tan lowers, and most today probably have rusted lowers. The Amazon (SU) green in 99/00 was similar but noticeably different, so you are limited to a couple years.
If you enjoy this type of work then go for it. Otherwise resale is going to be tough and hundreds.
