He doesn’t need to worry about the State of California. He needs to worry about the local District Attorney. I knew someone who had 53 Oldsmobiles in his backyard in Lemon Grove over the decades. Tall fence around so you couldn’t see them. However, Lemon Grove started to develop and someone made a complaint around 2004-2005 to the DA. He lost and ended up having to move them out of there. This fellow has two story houses around him.
So that Mustang was his first car. Looks like crap now and I can say that. Why? I have owned my first car, a 1968 Cougar, since I bought it off my father in 1969. The car is still pristine. Ones first car means something and should be treated accordingly. The condition of that Mustang tells me a lot.
As for that link to the 67 Cougar. Ther’s gold in them thar hills, err cars. Condition 5 Cougar, needs everything, unable to move, and needs a roof! Don’t care if it is a GT it is not worth more than $2000 and IF no engine and trans then even less.
