I have a 2004 545i, it's my first bmw. What is the timeline usually for aftermarket performance parts release for this car and what are some good company/websites that will release all-inclusive parts for this car? I've found an exhaust, intake, and springs. I don't think there is more than one company making any of these. I'd like selection and more variety. Any help?
