So... My 2006 E90 has me at a true crossroad. I would like to see more power out of it, but I'm leary of putting a great deal of $$ into it at 112k miles. While the thought of replacement has been on my mind for the last 6 months or so, I'm open to suggestions on upgrades to this beautiful vehicle. Is it worth spending the money to try and upgrade a 9 year old 330i with 112k miles? Or, do I look for an upgrade by way of a different model. If you have seen any of my past posts, the 8 Series, 6 Series, M5, and Alpina B7 have all been targets of my curiosity. Any input will be greatly appreciated. My E90 is comfortable, and I really enjoy driving it. However, the thought of $2-3k of upgrades, along with any wheel replacements, etc... makes me nervous with the 112k miles. Thanks in advance!!
