I drive a 1994 C180 and it is like an old man especially when accelerating and it really struggles to keep up speed. I test drove the 1997 C180 2 days ago at a car yard and it runs like a sports car, everything was so tight and felt like a brand new car. Mine is 190,000kms and this one is 101,000kms. When I stepped on the accelerator of the 1997 car, it does not react instantly with a pause of up to 5 seconds then it bursts forward like a turbo charged car and goes like a bullet with 2 big adults in the car. Mine will make a hell of a noise revving up and moves a bit sluggishly up to speed, but there is no thrill like in the other car. Can mine be on the way to the junkyard or the other has had some "illegal" and non-standard chip installed? The salesman can't say.
