Howard, I thought you had asked this before.
Anyway, i depends what you want in a Morgan, if a nippy runabout that's agile and fun a 4/4. If you want more power a Plus 4, and then a Plus 4 Sport. If I wanted a quick light car that was good for touring then I would go for a Plus 4 Tourer Sports with Suplex, the one I test drove at Williams was lovely.
If you like burbly V8's and a car that feels planted on the road then its a Plus 8 but will feel heavy on the steering compared to the above.
If your bag is screaming acceleration then a Roadster, the ultimate being a 3.7, but the earlier ones are quick as well. they can also be driven sensibly and are good tourers. Feel is between a Plus 4 and Plus 8 IMHO.
With respect to new or secondhand depends on your finances, if I had the dosh I would be tempted to by a new one at some point and just accept the initial depreciation, as I would keep the car long term. However I would say a one to two year old car thats done around 4-8k miles is a good option. I personally think a car that has done around 3k miles minimum a year is better than one that has sat on it suspension for most of its life.
I have brought both mine through dealers, both because I could not find one privately that I liked. The second one I also got a very fair deal and the dealer has been great. If you can find a cherished and cared for one privately at the right price for you then go for it.
