You guys might want to go to the Barrett Jackson auction in Scottsdale or the Auburn, IN auction and check out what some of these cars are bringing. A frame off nut and bolt restored MATCHING NUMBER 400 car (there) will bring a lot more than the prices I see above. On this type of concouse restoration...matching numbers will make MORE than $10K difference in what the car will bring. However, for a very nice driver car $3K to $5k premium is probably about right.
