all I have to say is when buying an old car dont trust anyone about its history

Yea, but most people don't listen to what you tell them anyway.
They are so thinking about what they are going to do with, it goes in one ear and out the other.
I sold a 69 Dart GT years ago. It was originally dark green.
I repainted it white. And when I sold it I told him everything I had done to the car.
He came back a year later after he took the quarter off in an accident.
"You never told me that was a green car!"
No.... you didn't listen.

It's no wonder the stories get changed.
