Debate's what it is about, Peter!
I think that, in your example, the age of the components is less (But not ir)relevant than the 'model year' of the finished van.
Your example is fairly clearly referring to a 2009 van "completed to current 2009 spec"
But wind all the dates back 1 year and if the van is still at the dealers in January 2009 (been there for a year), does that make it a 2009 van or a 2008 van?
I was offered some Euramobil profilas for my hire fleet at Peterboro show and they were being sold as 2008 models and were dearer than the prices of the profilas at Oaktree - hence the question about the true age of the vans and how they are described.
I don't have an axe to grind, just interested in the 'niceties' of how things are advertised.
Bit like Fiat offering panda for £4995 on the scrappage deal, when that price only applies to yellow cars, and sorry, that would have to be a factory order? Not what the ad says on the telly.
