Ted, I hope you're not gonna be in a position where you get the car running and then the price goes up.
If that's the seller's plan, your time and parts should be deducted from the new price, or you should be paid to walk away.
Maybe that's not a worry, but it's worth mentioning.
I've never bought a car that I had to work on before making the deal, but of course I don't know the whole story.
Just trying to be protective.
