I test drove one at Thruxton as Toyota GB loaned my Mkiv to display on the preview days.
I was very impressed overall but I didn’t really concentrate on the interior as I was always going far to quick
My summary would be:
Fast as standard so must be amazing with another 100hp!
Good traction & handling.
What I do say is that it’s a very good car but if the BMW involvement bothers you don’t buy one.
I would probably choose a m2 comp over the mkv as they have rear seats plus I think they look great
