Who has told a buyer that what you have is not what they need?

I have.
About 10 years back, there was a young guy (16) who wanted to buy a project car of mine.
It was a 73 340 auto Dart Sport.
He said it reminded him of a '70 340 auto Duster that his dad had back in the day and he liked the looks.
This car was pretty solid, but it needed quarters, interior work, and an engine plus a full suspension rebuild etc.
I told him a price and he agreed to it on the spot without pictures or anything (he lived about 500 miles away).
Then I said that I needed to talk to his mother and father about it and get their okay. (because he was a minor)
He made up excuses as to why I couldn't talk to either of them and said his dad had a towing company and he would come with the cash and a rollback truck alone to come and pick it up.
Oh, and it was to be a surprise to his parents that he picked up a project car all by himself and they would be proud of him.
I said ''No way will I sell you this car under these circumstances''.
First, he would have in effect stolen his father's rollback for a couple of days.
Second, he's buying a car without his parent's consent (illegal)
And third, they could sue my *** off if I sold him this car and knew about him stealing the rollback to do it.
And to top it all off, he only had enough money to buy the car and haul it home.
No money to restore it or for that matter, the skills.

When I finally did talk to his father about it about a week later (I phoned him) he was mad at his son and very pleased with me for not selling him the car.
I suggested that his son gets something reliable to drive and then save money for a project if he wants one later.
He agreed and that's what he did.
I never heard from either of them since.
