I didn't look that closely originally, I assumed he put a floor shifter on a car that was originally a column-shift car. But looking again, I don't see any evidence of a shifter on the column.
Did bucket seats always come with consoles? I guess that's a stupid question, because you would probably have a console if you had a floor shift, right?
And I agree that it's overpriced. My rule of thumb is that, regardless of modifications, you price based on condition. At best, the value of the modifications just equal the cost of returning to stock.
Maybe, since the car was in the family so long, he has all the parts still, and will deliver them in the trunk. Then all it needs is paint and wheels!
