Ah Mr Boshly, you've identified differing perceptions.
My perception of any car is what's underneath, because that's what interests me. The very essence of the trad Mog to me is the steel chassis and sliding stub axle suspension, and that's what I'm buying into. You're right to say it's not about the engine. The one key attribute of the trad is the engine is unimportant, except to the extent to which it delivers performance.
To prefer an Aero over a trad -(and here I'm surmising) the buyer must prefer the advanced engineering. Nothing wrong with that by the way. I think you're right that the factory see the Plus8+ as a trad, and to uninitiated buyers, it looks like a trad, so they will make certain assumptions when buying one.
But it's part of the Aero family. It would be interesting to know how much by weight and value it shares with other Aero models. The concept is fantastic but I don't see it as a trad because of my X ray specs.
That's it really.

There's a PS - and a headache. Where do I put these cars in the Concours.................
