So i have just recently purchased an SC400. Its my first car, i love driving it and want to keep it and i really want to put money into it. But i have this rattling noise coming from the engine. I woke up one day and as soon as it started it just sounded horrible. At first i thought it was one of my belts. My co worker told me it could be my catylitic converter. But my boss says it could be my starter. I also took it to an auto shop and all they did was tell me to pop my trunk and start the engine and they said it was the starter as well. Without even putting it on a lift. I am honestly not good with cars, so i wanted to know what you guys thought.
