Hello there, I'm Dave. I don't own a M3 but the other half does and I take care of all the maintenance on it for her. She isn't big on joining forums anyways. Its a 2008 M3 GS Sport Hatchback with the 2.3 and 5spd manual transmission. I see there is quite a bit of info to look through on here and if there is something I can't find, I will certainly make a post!
