I think it's all down to personal choice.
Like buying a car - you need it for personal transport, taking the kids to school, shopping, pleasure etc etc.
A Hyundai Getz (like my wife's) will do all the above quite adequately, so will a Porsche Cayenne. Question is, do you want to spend £5,000 or £42,990 (cheapest version). Maybe the Porsche will give you a bit more pleasure, maybe the Ionics supa-doopa will too, but is it worth the difference?
