I sold my 85 300TD wagon w/200k+ miles for $8200 a few months ago. Nice wagons with the third row seat go for a premium. They are a good alternative to a minivan, and the biodiesel buzz makes it an easy sell in the Pacific NW. I sold it via our local craigslist, to the first person who responded, and had two other people ready to buy if the first deal didn't happen.

I loved the 85, but my 87TD is a much better car. You don't get style points, but the economy and power is so much better. Once I found my 87 and drove it a while, I was more than happy to sell the 85.
