Not 100% sure what your getting at, however, can I counter it with another question - in which way is this 3 door design actually
more safe or
more sensible than 2?
I think the original idea, like the Rx8, was probably different, but I'd like to know if there was an 'oh bl**dy heck" moment when they realised that they could only supply one rear door, instead of 2? From what I've read about it from BMW, they seem to justify it as 'better having it than not having it', and that it isnt really an issue. And yes, for people that actually purchase the clubman, they will have already considered it a non issue.
Did any of the concepts for this car have a rear door? I cant remember.
I think there would even be a pretty big market for this car without a rear door, perhaps at a small discount?
There are a lot of things to like about this car, and it'll be a success. Just cant help thinking that whichever way you look at the doors, they dont do it any favours.
