Ever car is different, we all know that. But what is something about your car that is unique, and not neccessarily a sign it's about to fall apart the next mile?
For my Olds I've had forever until recently, the car would rattle after I hit so many RPMS. Turned dash inside out numerous times to try and find the culprit. Car ran fine, so never had any problems in the engine to troubleshoot. Turns out there were a couple loose screws that had worn down the threading in the holes for the rubber lining for the doors. Never got around to replacing them as they still did their job. It was hilarious to see the looks on people's faces though when they got in my car for the first time and then heard the rattling
