This is just a note for any southern Georgia / northern Florida folks who might be looking. There's an '84 300SD that's been in the local paper (and on cars.com) for a week or so. It's located near Thomasville, Georgia.
I took a look at the car earlier this week, and drove up there today with the intention of purchasing it. After reconsideration, I decided to take a pass on it.
If there's anyone in the area who might be interested, let me know, and I'll tell you what I know (and don't know) about the car. I have no particular affiliation with the seller, and no stake in the sale of the car.
