I've had several SUVs.
Previously in Singapore had a Volvo XC90 and an Audi Q7. Then had another XC90 in Norway which was sold off recently and still have a Land Rover Discovery IV which is in UK.
Primarily bought them for its ability to seat 7. I don't particularly like the seating and driving position of most 7 seater MPVs and generally don't like vehicles where the instrument panel is located in the centre of the dashboard which seems to be the case with loads of MPVs for some reason or another.
Also use them for work as I carry a lot of equipment and up manuals as well as printed plans with me so a SUV makes it easier.
Nothing about showing off, it is cheaper to buy an Audi Q7 or the XC90 in Singapore than it is to buy an A6 or S80.
Not much to show off with a Land Rover in UK, just about everyone has one where I live in UK and pretty sure 90% of them don't ever see anything remotely offroad beyond an unpaved carpark at the usual pub.
