Thank you for your replies.
I should have mentioned that I do not yet own a CT200. But I do ( or did ) wish to.
It's just that when I repeatedly got in and out of the drivers seat in a car showroom I had real problems. This was a real downer as everything else about the car I loved.
As far as I could tell the steering wheel was set to it's highest level.
I do not think that the seat runner extension would help.
Very intrigued to read Stormchaser's comment about having no problem. Perhaps I should try again in a different car.
