Elvis Presley's private planes to be auctioned.

The two private planes owned by late American rock-legend Elvis Presley - the Lisa Marie and Hound Dog II - are going up for auction.

The Lisa Marie, which was named after Presley's daughter, was bought by Presley in 1975 and refurbished to include a master suite with full-size bed and conference room.

Although neither planes are airworthy but have been on display at Presley's estate "Graceland"for more than 30 years for fans to tour.

They are being auctioned off by Julien's by sealed bids.

According to BBC reports,Presley bought the Convair 880 jet in 1975, two years before his death, and spent about $300,000, refitting it and renaming the Lisa Marie. It also features a bathroom with gold taps and a stereo system with 50 speakers.
