Doesn't matter really does it.
It's not MMC who are the arbiters, it's the buyers.
At the risk of droning on, where is the engineering link between the last Plus 8 with a Rover engine and the new Plus8+? Where is the common DNA?
The Plus8+ DNA is Aero. It's as simple as that. Looks like a trad from the side for sure. It will buffet the driver in exactly the same way as a 'proper' trad, and leak in all the same places as a trad. But to those who want the full experience of prewar chassis engineering, it can't deliver, whether it's perceived as a trad or not.
Lets hope it ticks the right boxes of enough buyers, whatever their perceptions.
