No offence taken! I currently have a M4, and i use the the pillar to pull myself out of the car very easily.
These grand coupes are 4 door, and im 6ft2, when i put the seat back to reach my normal driving position, the seat goes past the pillar and basically sitting in the back seats haha, so hope you can understand that? Plus when my seat was pushed back to driving position, we opened back doors on the cla, and my mrs is tiny, and she could not sit on the back seats as my drivers seat was probably less than a 10 inch gap between driver seat and rear seats.
And it was my mrs who picked the 2 series as she would be driving more often.
Hope this helps you understand 😉
Or I hope this passes your judgment.
