There is an Advent (short-lived Revell subsidiary) issue of the VW van, with pictures of the assembled Bed Bug issue on the box. However, the Advent kit was issued after the kit was modified for another issue, so the later issue is what will be in the Advent box. There is one of the Advent-boxed kits on eBay right now.
The Bed Bug issue is probably the most difficult one to find unassembled. I see more of even the stock issues for sale than of the Bed Bug.
