Usually, the rich Arabs stay in the best hotels and empty their wallets in London's most expensive shops, but they also cause problems with their unique super cars.
The streets of west London, Knightsbridge has long been considered a playground for the rich and famous.And every summer Arab playboys speed around its polished streets in garish super cars worth hundreds of thousands of pounds.
But one Russian woman has given the young men a run for their money by parking her crystal-encrusted Mercedes outside an exclusive hotel for the world to see.
At £25,000 many would consider the Mercedes CLS 350 an extravagance in itself.
Daria Radionova made her 2011 model even more luxurious, by covering it entirely in Swarovski crystals.
'I wanted to have something unique and do something special,' the 21-year-old business student said.
'The people who did it came over from Russia and worked for 12 hours a day for two months on the car.
'I am really happy with it and I am looking forward to driving it around.
'It has only just been finished and everywhere I go people stop to have a look at it.
'It gets lots of attention from people walking by and in cars. Sometimes I think they might crash.
'Everyone is taking pictures of it. When I sell the car I will give the money to charity.'
Parking outside the Levin Hotel on Basil Street near Harrods today, the car drew in crowds of admiring onlookers.
A manager said:
'We have seen a lot of unusual cars like Ferraris parked outside but I think this one has got the most attention. If you have the cash why not do it? It looks good and fun.'
Residents in affluent Knightsbridge have complained they are behaving in an anti-social manner, revving the cars and treating the exclusive area as their personal racetrack.
