I bought my 1990 300e 15 months ago. Today I am learning that my water pump is in need of replacement and it will be a bit pricy. What I can say is that with 190K miles, that is to be expected. Otherwise I can say that this car loves the road. It's 15 years old and yet everytime I get into the car, I still get that first time drivin' feeling. I encourage all who research buying an old 300E to get to know what you are looking at. When you come across a goodie, don't pass it up!
Fine leather that won't fade out as quick as Japanese or American leather. Solid wood grain, safety like no other car. On the highway I still get 26 MPG. Even with 190K!!
