Top 10 stars and their cars

1 Jay Leno: Duesenbergs

What a Doosey of a way to start this top 10 star cars feature! One of the world's most expensive cars and most sought after by Hollywood legends over the years is the American luxury Duesenberg. Talk show host Jay Leno has one of the biggest stables of exotic cars in the world, including six Deusenbergs, each worth more than $1.5m. They are so luxurious, they gave birth to the expression "What a duesy/doosey"! They have been owned by celebs such as Clark Gable, Gary Cooper, Greta Garbo, and Mae West. they have also been owned by millionaires Howard Hughes and William Randolph Hearst, criminal Al Capone and royalty.

2 Simon Cowell: Bugatti Veyron

They cost about $2m and are one of the fastest production cars on the planet with a top speed of 431km/h. The Veyron also launches to 100km/h in 2.5 seconds. The TV talent show judge is a good judge of a car with a garage that also includes a Ferrari F430 and Rolls Royce Phantom. He has also paid a deposit for the Rolls-Royce 100EX Cabriolet which is still just a concept.

3 David Beckham: Custom Rolls-Royce Phantom Drophead

The V12-powered Roller is worth about $1.3m in "standard" trim. But there is nothing standard about this Roller for the soccer superstar and husband of Posh Spice. For a start, it has custom-made 24-inch Savini forged wheels which cost several thousand dollars each. Beckham's number 23 is embroidered on to the leather seats.

4 Jerry Seinfield: Porsche 959

The reclusive comedian built a $1.4m multi-storey garage in New York just to house his 46-car collection, most of which are Porsches. The most expensive is his rare 959. Only 337 were built and only 200 of those were street legal. A 959 is estimated to cost more than $1m. Bill Gates also owns one, but neither he nor Seinfeld can drive them on the streets as they don't pass US emissions tests.

5 Jay Z and Beyonce: Maybach Exelero

Rapper Shawn Corey Carter (Jay Z) and Beyonce Knowles paid about $8m for this one-off German luxury sports car. It was commissioned by Fulda Tyres to test their widest tyres, but now Maybach is building the Batmobile-esque cars for general sale. The 350km/h two-seaters are powered by a 522kW twin-turbo V12 engine. The Exelero features in Jay Z's Lost One video.

6 Kim Kardashian: Ferrari 458 Italia

Now that she has filed for divorce from her husband of 10 weeks, Kris Humphries, her collection of cars could also be split up. The reality TV star has several cars, including a Bentley Continental GT, Rolls-Royce Ghost, Range Rover and Ferrari F430, to which she has added the F430's successor, the 458 Italia. In Australia they cost more than $500,000, but Kim's has apparently been specially pimped.

7 Paris Hilton: Bentley GT Continental

Of course, it's pink! The body, the grille, wheels, seats and interior trim. If that's not bling enough, it features a diamond-encrusted dashboard that is reported to be worth more than $250,000. In Australia, they cost about $400,000, but with a diamond-encrusted "PH" badge on the front, this one cost a whole lot more. The heiress bought it as a Christmas gift to herself in 2008.

8 Nicolas Cage: Ferrari Enzo

The Hollywood actor's addiction to cars caused his financial ruin. At one stage he owned nine Rolls-Royces. But his most valuable and valued car was the legendary Ferrari Enzo which was gone in less than 60 seconds at auction for a bargain price. The V12 sports car, named after Ferrari's founder, had a top speed of 350km/h. Only 399 were built. They can sell for up to $20m.

9 Ralph Lauren: McLaren F1 LM

The American fashion designer owns a huge collection of classic cars including the Mercedes-Benz 300 SL Gullwing Coupe, Porsche 550 Spyder, a Bugatti Veyron, two Ferrari 250 Testa Rossas and a rare 1962 Ferrari 250 GTO, of which 39 were made. While some might consider the 250 GTO the greatest Ferrari of all time, fetching up to $15m at auction, it's not as rare as the McLaren. Only five were built to honour the five McLaren F1 GTRs that finished and won the 1995 Le Mans 24-hour race.

10 Patrick Dempsey: Jaguar XK120

The hunky actor from Grey's Anatomy has great taste in cars, especially race cars. The aspiring racer has driven the pace car in Indy 500 and has raced sports car and off-road buggies. He is a co-owner of an IndyCar team and also owns a classic Jaguar XK120. They were built between 1948-1954 and successfully raced at Le Mans.
