Hi Bizfish,
I agree with Simon, "test the plus4". But I would go one step further, try a Roadster and a plus8 as well!! They are very different cars to drive. Buying new is nice because you can have a fun with the spec, but less so with the Sport models. Buying a used Morgan might increase your options and most Morgans are well looked after. They often improve with first ownership as the initial niggles are sorted. Whatever you do, I am sure you will enjoy it. Cheers J
