Being a Triumph fan, as well as Morgan of course, I dont think you can beat a Spitire, cheap to run, insure and maintain. Go for Mk3 or 1500 with overdrive ie 6 speed box. Easy to drive comfortable and plenty of room for 6 foot plus. Plus a turning circle better than a London taxi

GT6 and Vitesse good cars but too front heavy.

TR's, never owned one but TR5 would be favourite but more expensive than a Morgan.

Stags, all engine problems cured by now, original Triumph V8s more expensive than converted rover V8s.

MGC avoid like the plague, far too front heavy and expensive.

MGB over rated and expensive

Midget you have to be one to drive one!

Modern jap *rap, well obviously MX5 true successor to Spitfire in my opinion, but no-one has mentioned the Honda S2000 again never driven one but always wanted to.
