The Toyota Proace Verso would be a great people carrier for country roads. It drives like a big family car and will return an advertised 54.3mpg. It’s also backed by Toyota’s 100,000 mile five-year-warranty: vans.honestjohn.co.uk/van-reviews/toyota/proace-ve.../

If you want something smaller, the Volkswagen Caddy Life might work for you. It’s available with seven-seats and is much more compact than the Toyota in terms of width and height. However, it’s not as easy to get in and out of and bootspace is limited when all of the seats are in place: vans.honestjohn.co.uk/van-reviews/volkswagen/caddy.../
