I'm thinking again about putting my car up for sale. The current NADA value guide for a 1965 Formula S shows an average retail value of $15,780 and a high retail value of 24,360. Even a non-S car has an average retail of $13,150 and a high retail of $20,300. I know when I bought mine about 5 years ago average value was around $12k and high retail was $18k. FABO members know these cars better than anyone, so what do you think? Have the values on these cars really gone up that much?
