I think we must take BW seriously because she is the only witness who knew SL personally. It’s tricky because if you search for her name on YouTube a clip is there where she is interviewed about it (not the crimewatch clip btw) she does come across as a but ditzy and not too clued up. However if she is right then the car cannot be at Stevenage Road meaning it’s possible WJ saw it at 12.45 but it wasn’t there from about 2.30. As I have said before the case is like a Rubiks cube get one set of facts line up then others do not fit. Open question who do we believe more WJ or BW ? If you discount WJ completely and SL never went there where was she between 12.30-40pm and 2.30pm - 2.45pm? The sighting is only about a mile from the sturgis office it seems odd and hard to reconcile. Thoughts?
As you say it's like doing an abstract jigsaw with no picture.
My very first attempts at this was to try and fit all the witness statements together, this very quickly makes you realise that they're not all correct.
Regarding SJL's car, we know 100% that SJL's car was there at approx. 5.15pm, so if BW is correct it was heading towards Hammersmith at approx. 2.30pm, and back before 5.15pm. However, possibly not before 4.00pm as the workmen may have noticed it.
What doesn't fit if BW is correct and also WJ is correct in that SJL's car was in Stevenage Road sometime prior to 1.00pm is the fact that the perpetrator came back to Stevenage Road.
He's abducted and secured SJL somewhere near Hammersmith, he then need to get rid of her car, he could have abandoned it just about anywhere, why bring it back to Stevenage Road.
I've assumed that SJL knew her abductor and trusted him, so no one was alarmed (this fits with BW's account of what she saw), SJL agreed to drop him back at a location in Hammersmith and its at this point that his intentions become clear, but its too late she's inside and subdued without raising an alarm.
Now I have two possibles for this and one is JC, IMO he wouldn't have bothered to drive back to Stevenage Road (I don't think he's that clever), it would take a clever and calculated man to plan her abduction and disposal and one that had a very good reason want to keep her quiet.
Back to your question, WJ or BW, maybe both, with BW being the more reliable of the two, however, it would mean SJL never went to SR (which I think we generally agree) and went straight to Stevenage Road to meet the perpetrator.
Now comes the James Galway man and "the right ruck", just suppose he's telling the truth, it's not far off timing wise for the BW's sighting of SJL and the male passenger.
Okay, I've rambled a bit, but this is the scenario that fits the AL "you'll never find her' no one will" comment, he clearly thought DV hadn't got a clue and just lost his temper in frustration.
But, if this scenario is correct, then IMO so is AL.
