This is a question that is actually from the other side of the looking glass.
I currently have my 2005 Legacy GT for sale, and I have gotten 3 offers on it all lowball, and all 3 people said the same thing, that it needs tires (They have the summer left in them, and that is about it) and it needs brakes.
Now, the question I have, it is worth it for me to replace the brakes and tires on the car preemptively? Or is this just people using tactics to try to get me to lower the selling price. Like if I replace the tires and rotors, they will try to find some other reason to lower the price of the car, or do people genuinely want brand new brakes / tires on a car and they are willing to pay a premium to not have to do it themselves?
