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.
