Okay, so I bought a 1990 Mercedes 300E, but I'm a newbie Benz owner, so I'm still not exactly sure what I've got. I understand that my engine is a 103, and my body is a 124, but whenever I look on-line for parts, I'm given a choice between the 2.8-liter, the 3.0-liter, and the 3.0-liter 4-matic. Embarrassingly, I'm not sure where to find the size of my engine, nor whether its a 4-matic. Any clues would certainly be appreciated...thanks in advance!
