This is the location June 2007. Excavations started there that year or late 2006

CB's attire as you say doesn't fit with the location, but from what we can see neither does it on the VW image with CB in it. If the image was taken in May I stick with the BSJ area, if taken in June/July I think more likely it would be in the area CB was known to have been.
We know that the VW was parked at exactly the same spot on both the day/night time photos, we know that CB worked as a waiter in Foral and used to 'park up' the VW in the car park there, or close by maybe? Maybe CB was working and that's the reason it was parked in the same spot for some time..
Unfortunately the Google imagery from that time is not good enough to reveal anything in that area.
