I am in a BMW now because my Porsche was a ticking time bomb due to the IMS failures:

And again.. it took a class action lawsuit to get them to even publicly acknowledge the problem, much less fix it.

This was a known problem for 2001-2005 911's and Boxsters. I was also sick of the $350 oil changes.
That said, I would trade my F30 335i in on a new Cayman S in a heartbeat if I could afford it. Beautiful cars.
