Firstly welcome to Morgan ownership, sorry it is not as straightforward as you would have wished.
It does happen that a car can be manufactured in one year but its date of first registration is later. When was the date of first registration? This should be on the V5.
If this was 2007 , then I think you have a very good case under the Sale Of Goods Act. The dealer has misrepresented the goods offered and therefore you are entitled to something. If it was 2009 , then I think that argument might not apply.
What makes all this a bit more concerning is that there were a series of upgrades to the front suspension in 2008 that will obviously be missing on your car. I would point this out in no mean terms that you thought you were buying the upgraded model.
Is the dealer a Morgan agent? It doesn't sound like one of "the community" . This is a pretty small world and word gets around very quickly indeed. Some of the "newer" agents (in particular Stratstone) are not getting a very good reputation at all, so I do hope you have not bought from one of those.
No doubt others will be along soon to give more definitive advice.
