As a once (and hopefully soon) future owner of an E85 Z4, I'm looking for a bit of advice on seats and legroom. My earlier car was a 2.0 SE (seats with separate head rests) and I could just about fit in it with the seat pushed back and down as far as it would go. I've just had a test drive in a very smart 2.5 with M seats (integrated head rests) & it felt like it had an inch or so less legroom - gutted! Is this operator error or is there really less legroom in cars with M seats?
