For outright boot space, you probably won't beat something like a Land Rover Discovery. It has a huge 1137-litre boot when five seats are in use – although this drops to a paltry 258 litres when carrying seven people. For a more affordable alternative, consider a Skoda Kodiaq. Five-seat models can carry 835 litres of luggage, while the seven-seat version can take 765 litres when in five-seat mode.
