Features on a 300td wagon

[steverodie]

I have a 1985 300TD wagon. I wanted to know what some of the features on the wagon were. I don't know what the difference between the leather option and the Mercedes Tex. How can you tell the difference? Also I have some holes in the top of the rear seats. I'm guessing that they are for rear head-rest. If there are, does anyone know where I could get my hands on some. Were all the wagons equiped with the third seat? I have a spot in the trunk that looks like it's storage for one, but I don't see any spots for the seat belts etc....

Thanks.
