Unfortunately I am not going to be able to help here because I am cheap and feel that many of these cars are way over priced, however it looks like it has a XV engine bay brace in it or someone's version of one. If it is a XV brace, this car must have run or been worked on not all that long ago. A quick internet search shows 440-6 Cudas running somewhere between $80K and $190K, of course this is very rudimentary. As far as what it is worth now, others on here are far better suited to provide a more accurate estimate, however I would saw that if you are going for a complete high quality resto you are going to be looking at around $100K by the time it is done, so if you are thinking the car is going to be worth say $170K (just using this number), then you have to figure that $70K is your working window which is comprised of purchase price and profit. So depending on how much you want to make on it will leave what you should be paying for it. Given its condition and completely in my opinion I would say that car is worth somewhere around $30K. Now I am sure someone will jump on here and call this BS and say it is worth more or perhaps less, but like I said this is my opinion. Of course a lot of this has to do with its providence and documentation. The better both are, the more it is worth. If it has some unique options (above the shaker and 440-6), that could drive the price up. Ultimately for me, it is worth what you are willing to pay. There are some great restorers on this forum who can and most likely will chime is with better information. I am not a "numbers" guy or interested in original cars all that much, I prefer custom cars, built cars, etc but I respect those who are into original cars. Good luck.
