Buddy is selling a 66 Mustang Coupe for 10,000 with a 289v 8 in it. It has 15,000 on it currently. 3rd owner. Is this a good price for what I'm getting

This is hard to answer without any more information, but if it is a real 15k mile car, which would have to be proved, that would be very rare more likely it is 115k miles or more. Then the color, condition and configuration would be a factor. It normally takes us about $75,000 plus to to a concourse rotisserie restoration for a concourse quality car (#2+). Unfortunately no coupe is that desirable and worthy. As you know the sport roof or fast back is the one to have. We paid $3,500 for a 66 fastback hit hard in the front left with some rust issues and no drive trane. So for $10k you need a pretty nice car with everything in good shape and streetable. . Below is a break down of values: Excellent $22,000, Good $15,800 Fair $9,200. Then you need to deduct 25% if it is a 6 cylinder, 10% if is an automatic, but you can add 10% if it is a 4- speed (factory) and 6% if it has the Ford A/C system. I also would suggest you get Marti Report to learn what the car originally was equipped, what color it was and when it was built and where it was sold. The best source of documentation to authenticate your car. I think the web address is: Martireport.com Good luck

Oops I guess Kevin Marti only has records on Mustangs going back to 1967, his office may still be a great help

I find it hard that car has 15,000 original miles on it, something does not sound right

Casey, it is irrelevant whether the car has 15,000 original miles on it. That means next to nothing in this case. If it has 15,000 or a million miles on it, or if it has "issues" within it, the $10,000 price tag is low. Buy it before someone tells him what it's really worth. And don't depend on NADA values either, not on this one.

I have a 66 with 51000 original miles excellent condition exterior and interior. 289 runs great. What's the value?
