Windrush takes the truck to the spivs yard where it's broken up and put in a scrap lorry but the radiator grill they're seen throwing in is different to the one that was on the lorry.
A German staff car drives past the trucks but it is right hand drive instead of left.
Once they are all dressed as German soldiers and behind German lines the vehicles they are using should really be left-hand drive (continental), not right-hand drive (British).
