I just recently bought a comanchee. They said it was a 1988. The sticker on the door is faded and can't be read. The vin stamped on the dash is only 16 digits. A friend said to just put a 1 in front of it as it starts with JT. When i do this and decript it only it comes up as a 1986. Some sites even say its a AMC but its clearly badged as a jeep. Does anyone know anything about some that came with a 16 digit vin?
