you have to be realistic about what the buyer is thinking. He sees the bluebook value. Then he deducts the repairs from there. You MIGHT find someone who's more generous with their money, but I highly doubt it.
As for the plates - if a buyer is worried about that he's worrying about the wrong thing. I don't care what the license plates are. I care about the car. Is it worth the price, does the carfax check out, and was it stolen? If the answer to those three questions come out right, then I'll buy it.
Is it really $200 to fix the e-brake? I have no idea, but if I test drive it and you can't tell me what's wrong with it, I'm going to assume the worst, and that means I'm knocking off $200 unless there's evidence that it's not that expensive
