Just curious, are any of the prices on Hagerty or NADA even close to realistic. Number 4 car is 18-20. I have a 72 351c 2v mach and I just bought for 8500 in wrong color with nice exterior, no rust, new suspension, Engine ticking, ugly seats tear in carpet, and a bunch of little things that need to be done. Definitely a different car you are looking at so don't be surprised if it is much higher with 429. Good luck and I hope you get a great price. HAgerty only shows a bunch of 351C cars sold between 12 and 28K. No 429's. NAda shows the 429 as a 60% increase so they show between 20K and 85K depending on other options and condition. Ebay has one in your color with auto at 20,999 with reserve not met. This should tell what the market will bear site unseen. 6 day and 20 hours left. I like Ebay because this is what people around the country would pay you just don't know if they did. My car sold on Ebay twice for 10,900 and 12,000 but was never cashed out. That is why I got it for 8500 because he was frustrated and car needed love.
