In an ideal world I would have 3 Morgans. Sadly, pragmatism makes me choose one. My preference is for nimble handling in the lightest possible car - so 4/4 it is. The problem is that the best choice for me would be less than perfect for someone else - it is a very personal choice.
If you are unsure, find a dealer with a 4/4, a +4, a Roadster & a +8. Drive the. All and make a decision. Hopefully, one of them will surprise you and make your decision for you.
