2003 signature towncar w/156,000 miles, the smoothest, quietist ride, so quiet I hardly ever turn on any music. Just after getting it inspected to Jan. 2023 the engine started making a load rapping noise. If any of you have an experienced ear for what it might be I’d appreciate hearing it. I’ll try to attach a video of the sound. I love this car and hope it’s reasonably repairable. Not sure if it selected a photo bs video???
