interesting situation, guy finally tracks down his dad's Road Runner... and the owner won't sell, will only trade, so he has to find a similar or better car to buy to trade to the guy for his dad's car.

 

These are not rare, a 69 383 bucket seat Road Runner with the 4 speed...

I think the only way the owner will be happy and trade, is if this guy tells HIM to find the right car, and then pay for it, deliver it, and drive his dad's car home.
