Buying a 7-seater car isn't as easy as picking the model with the most space in the back - there are just as many different aspects to owning an MPV or 4x4 as any other type of car: how much it costs, the performance, the size of the boot and how much it costs to run.
There are all sorts of cars you can buy with seven seats, but the best ones are mainly compact MPVs, 4x4s and traditional large MPVs. In most models the sixth and seventh seats come as part of a third row of seats that can be folded into the floor to increase space in the boot. On some models this works better than others - and the need for a large boot might be more important to some buyers than others.
You might need to think about who it is that will be sitting in the rear seats most - some larger MPVs can accommodate seven adults, but many smaller cars will only be able to fit small children in the rearmost seats. The best way to think of compact MPVs like the Ford Grand C-MAX is as an occasional seven-seater, for use when there are extra passengers wanting a lift.
Caravan owners, who need to load up the family and luggage for a long summer holiday, often go for a seven-seater 4x4 like the Land Rover Discovery. These models have loads of space, and can take the family anywhere and everywhere thanks to all-terrain systems, but do suffer when it comes to running costs - so are best avoided if you're on a budget.
Choosing an engine can be a tough decision when buying a normal car, but with a seven-seater most of the time you'll want to go for the diesel option - in fact, many models don't even offer a petrol version. The extra torque and lower running costs that these engines provide mean you can keep up with traffic even with a cabin full of people and without breaking the bank.
However, some small petrol engines in compact MPVs might make more sense if you are only going to be using the extra seats occasionally - in a lighter car, a small petrol engine will be just as economical as a diesel.
