E90 325i Maintenance and Reliability
I'm thinking of getting a CPO, 2006/2007 model. Can owners let me know if there are any significant reliability problems I should know about? How much money should I budget in general maintenance and are there any major problems that I should be aware of. From what I've read on this form, $1-2K per year seems to be the general consensus outside of any significant problems.
In particular, I'm a bit about the 2006 year because it was the first year release of the 3-series design refresh.
