Have a friend and he's got two kids and another in the oven. So he's looking to get an MPV but doesn't know what he should buy. He's after one for between 6-8k ( second hand obviously). I told him Id ask in here as you lot are bound to know. Any recommendations? What are generally regarded as the best ones? My brother in law had a mercedes one for a bit and says it was the worst car he's ever owned.
