My numbers matching 69 convertible is worth at least $5000 extra because it's numbers matching.(IMO) A 400 car is not even a 400 car without the original engine(IMO). If you look at it that way I think you can see my point because a 400 car is worth considerably more than something less. All the appraisal books point this out. When I said as much as $10000 on a high end car that was the wrong(IMO). Now that I further consider this I think I was a little conservative. It could be as much as $50000 on the right car. Jim
