Mrs Image and I used to tour Europe back in the day .....but then stopped, thinking to travel to the more demanding places while we were young and tough, then pick up Europe again when the relative ease of getting about suited our changing needs .... so, unfortunately, my touring advice is of no good whatsoever (actually, that goes for a lot of my advice! 😄)
As for the vehicle, if you were touring to Malvern then the Morgan would be a must .... heading for the Ferrari factory makes your choice a no-brainer! .... though you could fully embrace the spirit of adventure and go to Italy in the Alfa!! 😄
Envious of the trip .... have a great time both of you.

Ps ... at the time (50 years ago) I liked Florence a lot ... but a lot can change in half a century !!
