Eldest child 16.5 years, youngest 11, one in the middle, would we be better off buying a 7 seater or a 5 seater and then in 18 months another small car the teenager could drive? We need more space for the kids to bring friends when we go away for a weekend, but cars are soooo expensive at the moment, maybe we should just hire a 7 seater when we need it. What would you do?
