I think in my opinion the real shame would be if the entry level Morgan is 60k! If the 4/4 is not replaced then that is approx 33% more than the current cost (39k?) for an entry level 4/4.
I remember just a few years ago a 4/4 started a lot cheaper, early to mid 30s which I felt was sensible. It certainly didn't do Morgan any harm over the years and allowed many people to justify and enjoy their cars, 60k is a lot of cash and I do fear a lot of enthusiasts will be priced out of ownership, how this will effect the future I don't know but it does seem to go against the philosophy Peter Morgan had, to provide affordable fun sports cars..
You are forgetting that the possible PlusThree could be the entry level Morgan.
