Hi, I am interested in a Mercedes of the series W123. I prefer a 4-cylinder (200 or 230E) petrol engine with automatic transmission. Since I want to use the car as a regular car, I am looking for a model that is as well preserved as possible. I would therefore be very happy about reports with experiences and tips and links to this model (no coupe). I would also be interested in whether the engine was fundamentally changed during the course of the model maintenance and whether it was suitable for these models. odelle already gave a CAT. Thank you
