I would go for a new LS, or 6 series Bimmer, but since I do not have that money yet, 300C is the best of all worlds.
No big problems with it. Nothing misalligned. My biggest issue is some rattling noise in the roof which I read is covered by a TSB, but I am lazy/no time to go and make that loose thing to get glued back. Could have more friendly NAV and dark seat option on C and nicer centre console's bin.
