For high-rolling drivers in the United Arab Emirates, no car is complete without a single-digit license plate.

The oil-rich country's wealthy elite are willing to drop millions of dollars to get their hands on one.

Dubai property developer Balwinder Sahni wanted a highly coveted plate bearing the number 5. He wanted it so much, he bid 33 million dirhams ($9 million) for it at a government auction earlier this month.

It was one of the largest sums ever spent on a license plate, although still lower than the $14 million record set in 2008 by an Abu Dhabi businessman.

Sahni found that his big purchase also brought him a lot of attention. He says he can't go out in public without people stopping him and asking to take a photo -- and some aren't impressed, accusing him of wasting his money.

"It's hard, people giving comments without knowing the type of person I am," Sahni told CNNMoney. He described himself as "a simple man."

The single-digit plates now adorn two of his six Rolls Royce cars. (He also has two more of the luxury vehicles on order.)

It's also not the first time Sahni has spent serious money on a license plate. He secured a No. 9 plate with a winning bid of 24.5 million dirhams ($6.7 million) at a government auction last year.

Since Dubai has no income tax, Sahni says he sees the hefty license plate purchases as his contribution to the public coffers. He says he believes the money will go to charity and toward improving the city's infrastructure.

"I believe in giving back," he said. "This city has given me a lot."

Dubai's Roads and Transport Authority declined to comment on how the proceeds from the license plate auctions are spent. The authority holds several a year. Bids can start in the millions of dirhams.

God is great. God give me money.. THIS MMM money no fit do me this kind money oh

For plate number alone,maybe the plate number is a pass to heaven or hell

He is a simple man in his own way.
But a truelly simple man will give that amount to a less priviledged and change a GENERATION for good.
