Found 3 Formula S Barracudas - Sitting close to 30 years

I just came across 6 1967 to 1969 Barracudas. The owner wants to sell all 6 together as a package deal. I don't have $ numbers just yet. Will be going back tomorrow for pictures and more info on them. I want one for sure, but can't afford to restore 6 of these cars. They have been outside on his property for close to 30 years now.
One 1968 Formula S is supposedly a numbers matching 383 car. Says he has title
One 1969 Formula S is supposedly a numbers matching 340 car. Says he has title
Two 1967 coupe V8s. One title, maybe both
One 68 V8 with title
One 68 coupe /6 with title
Not sure what is auto or 4 speed yet.
Anyways, I'm just trying to see what you guys might think those cars would be worth as a package price to offer him, or if someone might be interested in any of these cars if I do get them. Not sure of condition of all of them yet. Tomorrow will be FUN!!
Thanks!
