Does anyone have a Vauxhall astra (12 plate) and fit two of the Joie everystage car seats in. I'm sure the car seats will fit but I'm wondering if the middle seat will still be usable (for a smallish individual!) we currently have two maxi cosi pebbles and I can just about squeeze between them into the middle if they are fussy and wondering if this would still be an option. Would want to use them rear facing for as long as possible, not sure if this will make it harder or easier to use the middle seat.
