Hi Trev,
Please note that the suspension isn't BMW.
While not an owner of a CX, I have driven them quite a bit and can say the car as a whole drives extremely well. Soaks up the bumps, chassis feels very stiff in a good way etc. Is it `BMW / Porsche level? Far from. Is it a leap forward from the Trads? Yes.
I'm sure others who are owners will be along shortly. Due to the cost of the car, perhaps wait for a demo to arrive before committing.
Good luck
P
