“For sale is a 1944 GPW. This jeep runs and drives currently and is ready for you to take home on its next adventure. The body and frame have matching numbers, though the motor does not. The motor runs strong and is the same as original, it is a civilian engine which means it is 1946 or newer. All of the running gear and 4×4 parts are in working order and it is ready to hit the trail with the whole family. It features the rear seat option and is equipped with a strap on jerry can and spare wheel so you’ll never be stranded. Even the first aid kit is still with the jeep (though I wouldn’t recommend using it). No cracks in the windshield or on the seats.”
