I guess I can offer a thought. Although I don't have a car that new, I think the steering feel on the Morgan is 'specific to the car'. First off, the Plus 8 is heavier than my 4/4 and the steering is also a bit heavier. This was true of the 71 Plus 8 with the steering box as well.
Now on the two identical Plus 8s, 1985 and 1986, both with rack and pinion steering. They are surprisingly different with the 1985 having a lighter feel than the 1986.
So that being said, find a car and drive it. Find another and drive it. You will feel the differences.
Also, as others have said, try a Roadster. Good power and feel. I do know that there are after market power steering kits for this car. Not sure about the Plus 8s. Note: The power steering was added to a car driven only by a very petite woman.
Cheers and good hunting!
