Sorry but I just don't understand SBM's comments above - my Plus Six is probably the least boring car I've ever driven, or it is a least up there.
I have been touring in my 4/4 and it was masses of fun. The Elan Valley brought the best out of it and I can't think of a car I would rather have done that trip in. I will try the P6 next. time and let you know if I prefer it, but I somehow I doubt it.
I find Porsches far less engaging (this includes the GT3)
Just shows how we all want different things from our cars.
