well after looking at a 420sel for 4 days. The man who owned it finally lost my attention today. I came home went to Auto trader looking for another in my area. What I found was a 560SEL. I have never driven one of these until today. OMG. What power. Also I noticed lots of buttons I have not seen in the other cars. The back seat heats up and reclines, and in the front by the gear stick there is a horn button. what is this button for? When I press the steering wheel the horn blows. What's this extra button all about? Anyway this car has 188,000 on it. But is in mint conditon. Everything works, even the head rest and the door locks. Tell me what you all think. I have the complete history on the car also, as the mechanic for the owner is selling it. This car really moves like nothing I have ever driven. I was impressed by the 420, but this takes the cake. Also should I be looking for a Value job with this car having the millage on it that it has? it is a 1989 as well.
