$3000 is not a bad price, however if you want my honest opinion, I would not buy any car including this one that had a lot of body cancer if I was looking for a 1960's project car. A little maybe but a lot never. It is very costly to restore a vehicle that is rusted out and even when fixed, it usually comes back. Dash & carpet are easily replaced but cancer rust can and will repeat itself. You'd be better off looking for one with no rust. Just my opinion. So in answer to your question I would not buy it for a project car.
I'm switching to Q&A format to be notified of your response.
Without a doubt, the car is worth the price, but as for me, would I buy it for a project car, the answer is no.
This would be a better deal as a project car for $10,000 at this link:
The car above is numbers matching original 327 engine and 4-speed trans.
You have to think of how much you would have invested AFTER you restored it.
