Need help with WIW

I'm not asking to try to Squeeze every dollar out of these cars. I'm asking for a decent price to offer and so my friends mother could have an idea of what to ask for them. I would like to own a couple of these cars but want to give her what she deserves for her granddaughter.
Sure I could go to her and say I'll give her $1500 for 2 or 3 of them and she'll take it, but is that a cool thing to do?

no one is trying to get rich and get rich fast. There's so much more in parts, and his daughter will be taken care of.

As far as the sentimental trip, His daughter knows what every car is, what every part in the yard is and where they came from. A couple have been in the family passed down, the red 67 she was driving in as a baby. She wants to keep all her dads cars and property, but that's not a option for her. We where driving around in the 65 be for we had a drivers license. So this is very sentimental, especially because her dad was murdered and no one got to say goodbye.

lmao... I just knew you were going to zero in on that... That's not the point.
The point is, this, in the nutshell:
*Bundle it, include everything related to the cars.
*Price it where you have negotiating room, but it's still a good deal for both parties.
*Get as much money as possible in a lump sum.

Don't be afraid to say "NO" to the hawks, and don't be afraid to say "YES" to any fair offer.

Selling those cars and parts onesy-twosy could take months, and you never get a sizable sum of money all at once. Money dribbling in almost never works to your advantage.
