Well, it may be short-lived, but I've had some work done to my '88 560 SEC, and couldn't be happier. Car had two big issues - rough idle and would die at times, and ride was not good (nice way to say it). My mechanic adjusted the air/fuel ratio (he said it was running very lean) and installed new accumulators in the rear, and wow! It is like I bought a new car. Still idles a bit rough, but no dying and a great ride now. Also the overall performance has improved a lot. More responsive, it seems. I really like this car and hope to keep it a long time.
