I'm halfway looking for a nice MB wagon too, but I am discouraged by the level of mania I'm seeing in the market. Check out this 84 on eBay:

What is the purpose of bidding up a car to this level 8 days before the auction is due to close? The owner admits to some rust and a broken AC, what problems remain to be discovered? Insane.
I have driven Volvo wagons for 15 years. The 240 was a little slow but a great car. My 940 Turbo is quick and good looking but parts are getting harder to find and the car has almost no resale value, even with only 120,000 original miles
The MB wagons are appreciating in value, but reading this forum daily has put me on notice that if I buy one I will either be spending a great deal at the mechanics or more time in my garage. All of that is okay, but I'm not going to overpay at the outset for the privilege.
