So whats it worth?

[WTL]

Over the past few years, whenever my good old 91 Explorer had trouble I'd come to yall for help. Well this is the last time. On the way home for easter she blew a head gasket. It cost an arm and a leg to get her towed with the boat, and more to keep her in the yard there so I decided to pay the man to bust her out and take my chances parking her on the side of the interstate for a couple days. That backfired, someone broke in, took a grinder to the steering column and cut off the key tumblers and all that.

I'm thinking it might be that time.

It feels like I'm putting a dog down or something, but someone who buys junkers is interested. I want a price in the back of my head for what I can expect for this vehicle, so just throw whatever number you would think this is worth:

91 Ford Explorer, Eddie Baur. 4x4. 185,000 miles. 4.0 liter V6. Good tires. Blown head gasket and ignition cut off. How much would you say?
