Maybe NADA is basing their prices on what these cars sold for in the past. If they use B.J. as a thermometer than they are probably way off. Supply and demand. The market has leveled some especially for the non perfect cars. I think most people insure these cars for more than they are worth anyway. You are right about restos. To restore a 1969 6 banger camaro these days would probably still cost $60,000 if done perfect. So what would that be worth when all said and done??? Who really wants it?
