kd - I think you have a reasonable expectation for your money. Allow maybe $2000 for some repairs of leverwork, springs, hooks, and bolts, and you should be on the right trail. Most of the OE finish (pristine, say 2/100) = $40,000, much OE finish (slightly used, say 93-98 of 100) = $28,000, and some OE finish (significently used, say 84-92 of 100) = $21,000. Your price should get you somewhere around 60th percentile of current condition.
Please, let us know what you find. AG commands a great deal of respect, so we want to know what he says.
