Have had those $22 yard sale days too
Our first one got us like $300, the second less than half that, and the third one was like in the $22 range.
You guys have me torn. I would really like to see the SD go to a good home, to someone who will detail her and keep her shiny surfaces polished. Someone who's into buying some parts and working on the car. I am more in the category of "here's the credit card", vs. doing much myself. Lack of free time, and expertise make me just drop it at the shop, pick it up in a day or two.
I guess I could put new tranny fluid (Mobil 1 synth is a couple years old) in it, fix the seats, the AC, blower motor, monovalve... a number of things. At least 25 that one could count, if you count loose trim.
My solution is to buy a newer "used" Mercedes every few years or so. Hence the 300TE. The blue wagon. Very fast!
Faster than the W123, and better handling, in my limited experience with W123 wagons...
The SD is a sedan. A very comfortable one, but if you're 300 miles from home and want to buy a huge box of whatever, some things just won't fit in a sedan.
So there's nothing really sinisterly wrong with the SD, it's just kinda in the way and costing cash (about $100 actually) for insurance each month. I can drop comprehensive but it still would be $50 a month. Anyway, I was really shocked at the number of replies and the depth of the advice. I can really say that I agree with all of them
She's a nice ancient steel yacht, with a willing turbo 5 awaiting the order from your right foot. Been getting around 25 mpg highway. TE gets 17 mpg locally, low 20's highway.
I drive very fast whenever I can, which is increasingly seldom.
Anyway, thanks for letting me ask questions, and thanks for the excellent answers. This website is cool.
