I'm looking at buying a Z4 coupe as a car for the summer due to having some spare money available for the next 6-9 months. Our first baby is due next month and whilst I have an Audi A4 avant which will be our main family car still for baby and dog, I wondered if it would be possible to use the Z4 at all with the baby which would mean that the front passanger airbag would need to be deactivated - Is this an option that all Coupes had or only on those spec'd with ISOFIX fittings?
