Reminds me of the problem some of the small Gulf States (Qatar? UAE? whatever) have with expensive sports cars abandoned by native citizens who get a generous monthly stipend just for breathing - and then squander much of it on stuff like that.
The real story is actually more insidious. Those cars are not (usually) from locals, but rather from expatriates fleeing from (for example) Dubai. The thing is that the UAE have some very tough regulations on debt, and if you are in debt you can be taken to debtors prison. So, what happens is that there is some yuppie who was living the high life - nice luxury apartment, hot platinum blonde from Ukraine, flashy wheels ...maybe a Ferrari, at the very least something at Maserati level. Then they lose their job, and all that stuff (including the platinum blonde, if you catch my drift) was being actively paid for, and the person is left with negative cashflow and mounting debt.
I've been to Dubai, and if you go to the airport parking you will see some (very) luxurious cars parked there. You will notice some of them have layers of dust, and those are the ones that were abandoned by a fleeing owner.
They basically cut the losses and fled, rather than be in debtors prison in what may be considered a 'real' prison rather than a club fed.
