He has a supercar collection worth more than R50 million, with 30 luxury cars in his garage and more to come.With four Ferraris, five Porsches, three Lamborghinis, two Rolls-Royces and a Mercedes SLR McLaren in his collection, each with personalised number plates worth more than R1-million each, you would think this petrolhead was quite a successful man.But student Dhiaan Al-Essa is only 21. And daddy funds his car passion.A Koenigsegg Agera and a Bugatti Veyron are also to be added to the collection in 2011, spiking the value by 70% and costing Al-Essa’s tycoon father nearly R36-million. A nice 22nd birthday present, some might say. While some students spend their holidays at the beach or getting a summer job, Al-Essa spent his summer flying his cars to London, Montreal, Las Vegas and New York so he could go on driving tours with friends. The engineering student from Riyadh has a custom number plate with the number 070 for each car. And when his Ferrari 458 Italia was in the warehouse at Heathrow that burned down in August, he was forced to use his Mercedes. "The Mercedes McLaren SLR is my favourite. I love the way it looks and drives and it’s also been reliable for a car out in 50ºC temperatures."And don’t feel bad for him about the loss of the Ferrari, it’s being replaced by the new Ferrari 599 Roadster, production number 70 of 70.Al-Essa also said, "I love speed but the limit in Saudi Arabia is 120km/h so I’m pretty limited. When the Bugatti arrives I hope to take it to Germany where you can drive as fast as you can."Sometimes life just isn’t fair.
