I just checked 2015 diesel vehicles on my local craigslist (I refuse to use facebook, though I know that is where most cars are these days). A bunch of trucks for $15k-30k, and a few VWs for $15k. So then I search for electric cars from $10k-$15k and found nothing at all! YMMV in your local areas, but you will likely find the same: in the price range of a 11 year old diesel you will find nothing: EVs were still rare niches 11 years ago.
I did find a few eGolfs and leafs for $5k-8k, but in my experience if a car is that cheap there is a reason for that, so I assume they are unacceptable. There is a chance OP has a diesel truck because he needs a truck which in turn means they wouldn't work even new (the F150 lightning perhaps would)

The reason is: no one wants them. Three years ago we sold an OG Leaf my spouse’s coworker for $3500. Battery was about 80%, but otherwise the car was flawless. All the buyer needed was an around-town car, and the old Leaf fit the bill. Leafs didn’t go very far on a charge, ergo they won’t have a whole lot of miles in them, and they were otherwise reliable. If it’s all you need, I’d recommend one for cheap.
