I finally did it - purchased a 2004 Carrera coupe with 18k miles. I have put about 8k miles on it, and have noticed that a mild rattle in the driver door has, over time, become quite loud and annoying. It seems to go away if I press my elbow hard against the panel. Is this a common problem that anyone else might have encountered ? The car is a joy to drive, but the rattle is very very annoying !
