What battery problems? How many electronics are you running to drain the battery in 15 minutes? Ive had the '09 d since new, have let it sit in a -20* garage for a week without starting and not driven it for several weeks at a time. Two weeks ago it, it didnt move for a week and a half other than cranking it 4 times to move a total of 30 feet in and out of the garage to detail. Never had an issue. Maybe I'm lucky but still......

I agree with the rattles though. My rear seat goes through random spurts where it will rattle like crazy and then it magically goes away for a while.

To each their own, but to me it sounds like you need to justify the expense of dumping a new car because you're bored.
