Oh, they can afford it, no problem. Those guys treat them like hire cars. Thrash it 'till you're done, move onto the next thing and forget about it. The next thing is probably a Lear or a 150ft yacht, so the Jags no biggie really. I live in London and when I go into town (Knightsbridge, Mayfair, Regents Park area) they're all over the place. Aventador with neons anyone? McLarens, Ferrari's, Aston One Seven Seven, Bugatti's all over the place. Many are Mansori modified or similar, lots of wraps and paint jobs, and loud exhausts too. Cool to watch.
Sometimes the police impound them as none of them have insurance. Why would they? As far as they are concerned they could buy your whole life in a heartbeat. There is a You Tube channel called shmee150 - he shows you what Russian's and Arab's get up to in London with their toys.
