I guess I just don't see any significance at all to hiding or "X"ing the check digit. It's a computed digit, for cryin' out loud, the instructions for which are here multiple times in EliseTalk itself. Display it or don't, it makes no difference at all to anyone harvesting VINs.
VIN in full, with check digit obscured, or just the full serial number and year are all totally identical from a havesting/privacy point of view. If it makes your sorting easier, just use X for everyone's check digit -- you can always recompute them later.
If you want to obscure or blur the serial numbers, "X" out the last digit, one of the meaningful serial numbers. That way you know what batch of ten the car is in, but no more. That seems reasonable.
Otherwise, I'd just make up a VIN that's "close enough" within +/- 10 from mine and use that. The check digit is just a speedbump.
