Thanks for your response, MM.
On one occasion, I've refused to accept a vehicle from Ford's Dagenham plant until they supplied the missing valve caps. Things like that should definitely be present when the vehicle leaves the factory. The problem is that not everyone along the line checks the vehicles as well as they should. Additionally, some items might be present at one stage of checking but mysteriously 'disappear' prior to delivery. (e.g. your vehicle may have had the rubber flooring at one point. A vehicle inspector will have correctly signed that everything was present. Then someone who works for Ford has a mate who needs the rubber flooring replaced in his van and your property 'takes a walk'. The transporter driver thoroughly checks the vehicle for things such as scratches to the bodywork but probably never thinks to check the interior of the vehicles).
When I refused to accept that van without the valve caps, Ford staff simply removed them from another vehicle. If the guy who collected that vehicle wasn't as thorough as me, the second vehicle will have been delivered with the caps missing.
Incidentally, if you think that Ford factories are super-efficient places, you're sadly mistaken. I once went to collect an Escort van, only to find that the battery was flat. No problem, of course. Ford have thousands of batteries and a replacement was found almost instantaneously. The only problem was that, desptite having the whole of the resources of their Dagenham plant available, it took 40 minutes before anyone could find a spanner! :-)
