Cadillac Seville

I bought this car for 4000 and i was planning on buying a new car. I am selling it for $500 because the engine doesnt work/ the timing belt doesn't work? i dont really know alot about cars but i know that i dont have the time to put into it so someone who wants a project or needs cadillac parts i will sell $500 OBO its in GREAT condition other then the engine.
