Please can anyone suggest what is a comfortable time/distance to drive in a Morgan in a single session/day (ignoring ablution stops/char breaks)?
Much would depend on how dodgy your back is....
I have driven from coast to coast in France in a single hop in my previous Morgan (3.7 Roadster). It was not hugely comfortable and my back suffered afterwards.
In my case, even though I am now driving the more comfortable Aero +8, would probably be 4 hours absolute tops. When I next do a Continental tour, that is what I would plan on.
