Every project owner eventually says the same dangerous sentence: maybe I should buy a parts car. Sometimes that is the smartest move in the whole build. Sometimes it is how one unfinished car becomes two.
The first question is what problem the parts car actually solves. If your project needs model-specific trim, rare interior pieces, glass, brackets, or small hardware that no catalog carries, a donor can be gold. If you are buying it because it seems too cheap to ignore, be careful. Cheap cars are very good at becoming expensive storage.
Make a list before you go look at it. Write down the parts you need, what they cost separately, what condition they must be in, and how quickly you can remove and store them. If the donor does not clearly beat that math, it may not be a deal. It may just be a second title, four more dead tires, and another conversation with your neighbors.
Condition matters on a parts car too. A rusty shell can still be useful if the trim and drivetrain are good. A complete-looking donor can be almost worthless if the same parts failed on both cars. The more specific your needs are, the more ruthless you should be when inspecting it.
Also think about the endgame. Once you pull what you need, what happens next? Can you sell remaining parts? Do you have space to keep it without it becoming yard art? Is there a recycler nearby? A parts car without an exit plan has a way of becoming permanent.
The right donor can rescue a build from months of hunting. The wrong one quietly steals space, money, and motivation. Buy the parts car only when it moves the main project forward. The main project is the point.
