we have 2 kids under 5 and t the moment have 1 car 5 seater. Now, when we are taking my DC's friend for a day out or want to go a long distance, then feel a bit cramped in a that car. do you think it is better to upgrade to a 7 seater. I think we will need to pay 3000 difference ( on part exchange). I use car to travel to work everyday. so the main use of 7 seater would be week ends and holidays. please share your thoughts
