Although Richard does do a very through prep job, and gets people to pay for his work. Leaving out the high priced VXs from someone who specializes in them seems to be counterproductive in this situation. Don't negotiate with yourself.
Note that all of the asking prices are significantly higher than NADA. I'd be tempted to call a couple (or tell the adjuster to call them) and see if they would take NADA, but then I get obsessive.
I am always nervous about buying any used car because I don't know the history. I have paid more to repair a car I knew than it was theoretically worth, because I was confident of the rest of the car. It worked out for me.
