I am considering buying a 1984 190E. My only concern is that the engine has a tapping sound that increases in speed as the idle goes up. The salesman says this is normal. Is it? or is it something that might need major repair? Otherwise, the car runs great. pickup is quick and it seems to have a lot of power. It also idles smoothly. Any feedback would be greatly appreciated.
One more thing that I noticed while test driving this car is that the first time I went to use the directional, nothing happened. I turned on the hazard lights for a second and then tried the directional again and it worked. Just a fluk? or electrical problems? As you can probably tell, this is going to be my first Mercedes, I've always driven caddies but I fell in love with this 190E when I saw it on the lot.
