She's just wanting a "newer" car. 95 or newer. Yes, I have always had very good service from diesels. I like the low maintenance and dependability. But now the newer MB diesels seem to be of less quality that I'm used to.

I know the 124 E-class body's had wiring harness problems. If that's been fix, are they still good cars? The S-class (140) looks good and the wife wants the larger car, but I've not heard a lot of praise for these cars.

I know I'm asking a lot, I'd just like as much info as possible to make a wise decision.
