A bit more on the VK3. It does not show up on anything for 442. I have a GM document that states that last minute changes to options and stuff dated 7/19/84 (superseding the W42 planning document from 4/23/84). Target pilot dates for 3 units (probably one in each color) by 10/1/84, and target production date to start 10/22/84.
I'm still looking for my dealership release/press photo showing a b&w photo of a gray 442 which IIRC, shows the license plate holder. Can't seem to find it at the moment.
85 442 ad- shows nothing up front where the license plate holder should be. They shaved it for the ad.
They did a pre-production 442 for the mini-brochure "Three for the Road" which does show a one-off bumper tab cover, however, this was not a production option. There was no box to check or uncheck when you ordered one. You just got one. And at the time I ordered mine, it came with one anyway, although SC had only a rear license plate. To me, probably the most annoying thing about this fold out is the fact they red-bombed the interior picture. Looked like Jason Vorhees slashed up a bunch of teenagers in there. The Dark Claret interior is such a deep burgundy it probably wouldn't have showed up very well. They could have used gray. They even "painted" the cross bar and the silver horn button trim ring of the steery wheel red.
