I believe that European Capris shared bits with other Euro Fords-things like motors, suspension pieces, etc. Problem was, none of those cars ever made it to the States, at least not in any numbers worth mentioning. Because they're much more common in England and Europe, parts both new and used are pretty easily available (and most service items are stocked at whatever the British version of Pep Boys is. Halfords???). The whole situation reminds me of the last time Ford tried to do this, with the Merkur in the 80s. After the first couple of years you absolutely could not find parts for them, at all. I kinda liked the XR4ti I test drove way back when, but the lack of oil filters put me off. Strange, when I could buy MG Midget oil filters at Ace Hardware....
