I’ve seen prices all over the place, Depends where you’re located at and if you want to sit on it for the right buyer or move it aggressively. I’d say it’s worth 18-25k. Sometimes a vehicle that sits for a long time can have as many issues as truck that is driven regularly. If you’re located on the west coast I’d be interested with further information.
That’s a tough one, hard to find a stock one with that low of miles. But it’s your truck so you can do whatever you’d like to it. If you see yourself selling it though just keep it tasteful and don’t cheap out.
