I miss the 67 I had. Bought it from my uncle about 10 years ago. It had to go mostly to appease the spouse and partly because of money reasons.
The 1967 Cougar was a groundbreaking design. I can see why you miss it.
They are a little expensive to restore but not as bad as a European car of the same vintage.
I scan www.hemmings.com for old Cougars, Mustangs, and other 60’s Mercurys and specific Fords weekly.
Still underpriced for collector cars.
