Justin Bieber is quickly rising up the ranks as one of the most car-obsessed celebrities. Just weeks after receiving a personalized Cadillac CTS-V from West Coast Customs, the 17-year-old "Never Say Never" star has added another impressive ride to his growing collection. According to The Sun, Bieber is now the proud owner of a customized Range Rover that cost him more than $159,000.

Included in the long-list of features in the SUV is a stereo system worth upwards of $79,000. But there is much more than just an impressive stereo. Among the other highlights are a high-performance Cosworth engine, custom paint job and a leather interior. The finished product is the work of Project Kahn, which has also customized cars for stars such as Wayne Rooney and Katie Price.

"Justin loves his motors even though he's barely old enough to drive," a source close to the situation told the newspaper. "His girlfriend Selena Gomez will be well impressed with his latest. It's the business."

Although Bieber has an ever-growing collection of impressive cars, including a Ferrari F430, he still has a long way to go to catch some of the celebrities with the biggest fleets. Perhaps the most famous car enthusiast in Hollywood right now is Jay Leno. The venerable talk show host even has a 17,000 square foot garage that houses vehicles ranging from a 1906 Baker electric car to a powerful 2006 Corvette.

Bieber may be far behind Leno, but he certainly is well on his way. His burgeoning fleet is especially impressive when one takes into consideration that he has only been on the road for little over a year.
