I am a new BMW CCA member and my son just joined Sunday. Including my son, this is what we own in the BMW world: 2003 325i, 2011 BMW 335i (sport package), 2011 BMW 335i (M Sport package), 2013 528i. I have owned a total of 6 BMW's in my lifetime, including my wife's 528i. We are looking to rebuild the 2003 325i and make it a race car. Any advice would be welcome. I live in the Birmingham, AL area and my son lives in Atlanta.
