You aren't far off on pricing, but in my opinion, as it sits, to sell this you will need to be closer to $6500-8000. If you find the right buyer you may get a little more. It definitely looks solid and the hard top / doors add value. Rust isn't bad at all. I would invest another $500 to get it running and driving, clean it up, and market a bit more. Invest that money and your return will double. If your 40 was a driver (still needing regular work like all 40s need, but was able to go down the road on it's own safely) I'd say $8-9k is very fair.
Just my thoughts. Good luck. I hope someone picks this up that will fix it and drive it.... not try to flip it for a ton of money....
