When will the time capsule car that was buried for Tulsa's Centennial 1998 be dug up?

In celebration of Tulsa's Centennial 1998 (Tulsa was incorporated on January 18, 1898), a time capsule was buried on January 17, 1998 in Centennial Park, located at 1028 E. Sixth Street (Sixth and Peoria). Stored in a vault above the ground, the purple, Chrysler Prowler was enclosed in a seamless plastic "box," specially made manufactured here in Tulsa for the time capsule. Officials drained the oil and other fluids, replacing them with synthetics that won't degrade, officials said. And the vault itself was filled with an inert gas to keep the exterior in good shape. This capsule is to remain buried for 50 years and will be dug up again sometime in 2048.
Various items were placed in this time capsule by the Rotary Club. These keepsakes included items such as: a teddy bear, a pair of in-line skates, an envelope with four crisp $50 bills, a cellular phone, a postal uniform, a business card from an Arabian horse dealer, a family photo album, a case of Weber's Root Beer, the face plate from an ATM, and a large collection of Beanie Babies.
