Billionaire Warren Buffett is putting his 2006 Cadillac on the auction block in order to raise money for a charity he has supported for a long time.

Buffett's Cadillac DTS sedan will be sold online starting on February 11 and ending on Feb. 19 at Proxibid's website, according to Reuters.

All proceeds will go towards Girls Inc., a charitable organization dedicated to offering recreational and educational opportunities to girls in Canada and the United States. Buffett's daughter, Susan, is a Girls Inc. director and first lady Michelle Obama is an honorary board chair.

Buffet, 84, is one of the world's wealthiest people and most successful investors in the country. He decided to replace the DTS last year with a brand new Cadillac XTS.

The car has logged just 20,310 miles so far, since Buffett commutes just two miles from his home to his office in Omaha, Nebraska where he runs Berkshire Hathaway Inc, according to Proxibid.

The 4 door sedan has a leather interior with heated and cooled power seats, a parking sensor system, automatically dimming side mirrors, front wheel drive and is equipped for satellite radio.

Berkshire owns nearly 80 businesses, like Dairy Queen, Geico auto insurance and BNSF railroad.

A 2006 DTS in excellent condition similar to Buffett's vehicle could cost around $11,500, but Buffet's car is expected to go for a lot more, according to Kelly Blue Book.

For example, the chance to have lunch with Buffett last year was auctioned off for $2.2 million, which went to The Gilde Foundation, a San Francisco anti-poverty group.

Though the winning bidder of the DTS won't get to have lunch with Buffett has signed the car and will deliver the keys personally if the buyer drives to Omaha to pick them up, Proxibid said.

When Buffett sold his 2001 Lincoln in 2006, the winning bid was $73,000.
