ok so i have a 02 tahoe and i noticed that it doesnt have the tahoe written on the drivers side door, passenger door, or on the trunk door....i am the 2nd own and i was wondering if the previous owner took them off or Chevy just didnt put them on the 02 models

Z71's never had them on the driver/passenger doors .. I think the '05-06 are the only ones with Tahoe on the back from factory ('01-04 had Z71 & Chevrolet).
