Well I suppose he may haunt me for this, but here's the story. Mark liked to swoop into troubleshooting threads every now and again and drop some amazing official Isuzu document that somehow only he had. On other occasions he would write posts that simply alluded to something he had in his stash, then refuse to provide it when asked. So at some point I got really irritated at his flaunting and started publicly pushing him to make his stash available to the community at large. In particular he had a CD that contained a program where you could query an Isuzu master VX production database by VIN and see the original exterior and interior colors, date of production (not in-service data but when your VX actually rolled of the assembly line), etc. It would have been absolutely invaluable for establishing how many VX's remain in production, which would have been useful if/when our trucks reach collector status. As an example I spent hundreds of hours compiling an ultimately incomplete list of Foxfire VINs from AutoTrader, eBay, CL, etc., when his CD could have provided a fully comprehensive list in seconds. This is assuming the data on the CD could have been extracted into a list format, but since Mark refused to post the CD contents to his cloud drive or take it to a local data management company (I researched and provided him a list) we'll likely never have access to that data ever again. He did finally provide most/all of the other information to the community, but it took a lot of harassment.
I hope Mark rests in peace but I also hope everyone here will remember his story as a cautionary tale of the consequences of hoarding any VX info you may have. If all you have are hard copies, get them scanned and posted. And even if you only have parts it would be a good idea to make sure a loved one knows of this site and can post them if something happens to you. These recommendations may sound cold but frankly if we don't follow them we may be relegated to "barn finds" as the only path to new info/parts.
RIP Mark.
