Friend has a Freelander and we were given a BMW X3 as a rental in Germany last time we were over. They’re both nice, luxury, cars (but then they should be for the money). Interior space is no better than a normal car and boot space is pretty shocking on both because the sill is so high. The mate puts his kids (admitedly oversized) pram in the boot and it’s full. They’re both BIG vehicles though. High, wide, long.
Estate = same interior space, better handling, better fuel economy. MPV = same body size, masses more interior space, probably still better fuel economy as you lose the weight of the extra transmission.
Relatives replaced a Passat estate with a Nissan X-Trail when he needed something higher that would be easier to get in and out of. Shocked by the fuel economy. Currently have a Golf Plus – high driving position, *masses* of interior space on Golf floorplan. Works really well for them (ex-farmers, still live miles up a tiny lane – see no need for 4 wheel drive on the road….)
