Just purchased a 2004 330i zhp mt 145k miles. Silver with black alcantara interior. I'm in the greater Seattle area. Migrating from a 1999 z3m roadster 57 k miles. Wanting more of a daily driver. Looking forward to getting to know the car. Car came with cold air intake, ss headers and 364 differential. Never drove one with the 307 original diff. Thoughts on this set-up? Thanks and looking forward to being a member in this community.
