I think you will be surprised at the fuel economy of the recent classic cars. The 44 sport with the 1.6 engine I got well over 40 to the gallon, I still get high 20's and better in a Roadster. The Plus 4 exceeds your expectations and has well over 30 to the gallon.
On prices you are right, Morgans just seem to hold their prices strongly year on year. Once you are an owner you will be pleased about this.
Your plans for some touring suggest you might want to consider later cars (2001 ish onwards} with the better and simpler hoods. I have had both and the original type was not fun putting up in a hurry, although both versions work fine.
If you intned to do any kind of serious motorway driving ( or continental equivalent) you might find that the extra mid- range torque of a Plus 4 ( as opposed to a 4/4) might be what you 're looking for
