I loved My '63 4/4 Series IV. I had rebuilt it from a "Basket Case". Nothing special about it. So long as the road had curves I could keep up with any Morgan, any year and any model. On the straights it was lacking. 63HP I think. The Modern 4/4 has over twice that power. If kept light whats not to like.
I do not like "Aero Screens". Look nice but not enough protections.
I like the idea johncc has. I would prefer more than 600 miles and wonder Why so few but in a LHD country I would not own a RHD car. (I once owned a '54 Bentley "R" Type - hated RHD)(I did have a friend with a RHD Morgan and He said NO PROBLEM) If I bought a RHD I would convert it to LHD. If You are DIY(Do It Yourself) it should not cost much. If not maybe the used 4/4 is not for You.
