As his friends finished swapping the stereo as well as the tires, Jeff finally broke his silence. "You know that car is actually my brother, Jeff". His friends stared at him in bewilderment. "I can prove it", he continued as they got Jeff of the lift. Greg rushed to the car and turned the stereo to Jeff. "Thanks buddy, it's nice talking again", was the reply. "Naw...", said Cliff, "that's just some elaborate hoax."
"Well then, let's go home and I'll show it to you", offered Greg as he was gesturing his friends to join him. Reluctantly they drove home to Greg. After getting out of the car, Greg made sure the garage door was closed and everybody was out. "Just wait here and I'll show you.", he said before rushing off to his room where the Chronivac was.
As Jeff felt the changes coming to him, he remarks, "You'll see that I'm a person". At first Jeff gradually lost all his details, seams at he doors or around the engine filled up and disappeared. Gradually his whole body was getting a more and more round and shrank quite a bit. His tires seemed to disintegrate, forming fingers and toes again. His eyes and the grill in front of his engine were moving together and gradually formed something that was more and more looking like a face. His body flattened to more and more human proportions and joined the rest of his body as arms and legs were starting to form. After a couple of minutes Jeff was back as a human down on all fours. He stood up and stretched, "Man it's good to be back". Suddenly he realized that his hands and feet were feeling strange. Looking at them he noticed that he seemed to be wearing black rubber gloves and boots. Looking at the soles he saw that they had tire marks on them. The same was true for his hands, though the pattern was much finer there. Then he saw that on his chest he had the glowing displays and controls of his new stereo. "Must be my upgrades", he pondered before realizing he was naked. To further his embarrassment his member was quite erect.
His friends however were shocked, they saw a jeep turning into a human again. "Come I'll show you how it's done", offered Jeff and directed them upstairs to Greg's room.
