No experience at Boreham Wood I'm afraid, but mine went through at Peterborough no problem at all.
The car didn't need to be finished, so long as the body is attached and all the major components, engine, gearbox, axles etc. are fitted it shouldn't be a problem. Mine was at this stage -
As they've now done six or seven of these inspections at Peterborough it might be worth making the journey if the Boreham Wood tester doesn't know what he's doing
Good luck!
