Definitely go and check out the DS7 yourself.
I wasn’t one bit impressed. Its very small for such a large car. The boot is very horizontal. I’m personally not a big fan of alcantara and i thought it looked particularly poor in the showroom car. I wasn’t impressed with the fit and finish of the car, and for me the interior styling is very marmite, i.e. love it or hate it …….. i didn’t love it.
Its a very personal thing with the DS …. you may just love it.
