To be honest, its probably worth a lot more stripped-down than it will ever be as it sits. I'd say $3k is what you can expect to get for it in the condition you describe with those miles on the chassis. You can remove most of the aftermarket parts and still get around that same price. I think you have another $1k in parts value if you wanted to take the time/effort to remove them and replace with oem.
If you sell the HT separately you have another $1k, but you'll need a softop. I have a good tan top on a frame I can sell you cheap (install too) if you want to be able to sell the top.
