See SWNS story SWRICH; A supercar fan has laid claim to having one of the world’s greatest car collections – despite being just 21. Dhiaa Al-Essa has a supercar garage made up of 30 motors totalling more than £4.5 million – a value which will almost DOUBLE over the next year with new additions. Ferraris, Rolls-Royces, Lamborghinis and McLarens adorn the drive of the Saudi’s multi-million pound Riyadh pad, making it look less like a house and more like a Monte Carlo casino car park. „The Mercedes McLaren SLR is my favourite,” says Dhiaa, speaking from his New York mansion. 30 August 2010
