My Motability Ford Focus comes up for renewal in September and I'd like to consider the upcoming Ford B-Max. I get pain in my left leg whenever I have to raise it, so getting into the front passenger seat of the Focus, especially lifting my left leg in, is a painful and slow exercise. I’m wondering whether the sliding rear doors on the B-Max would enable me to get into a rear seat with a bit more ease. I’m 6 feet 3 inches tall. I’d welcome your opinion, and perhaps whether you think there are any other models I might consider?
