..... I hate to hear about abused wagons!
I picked up a 95 w124 wagon earlier this year, needed new struts, and had the wrong (undersized) tires on it, but other than that, the car is almost flawless.
PO's had every receipt and record from day one, along with all the keys and books.
At 141,000 miles, the car runs exceptional, and gets around 20mpg, mixed.
I wish you luck on your search, just hold out for the "right" car
