Just got back from the afternoon outing, dog walk first followed by a van crawl. Not only did I not see the target vehicle, I also did not see a garage door capable of accommodating a van taller than my own VW Westy that barely fits under the seven-foot header of a standard garage door. It might be over there, but they must have painted it full camo since the ad was posted. Sorry I don't have more encouraging results.
If you ever do make contact I'd be glad to scope it out for you in general vehicle terms; I'm no Sportsmobile specialist.
Actually, now that I look at the map it's centered more along Atlee Road (SR 615) while I came in from the Meadowbridge side and saw mostly that quadrant. Maybe I'll make another pass further east tomorrow.
