Oh forgot to update this thread with the new car!
I purchased a CPO 2003 325i Black/Black Steptronic with 39,730 miles on her. The car is amazing! The M54 engine is an upgrade from the M52.
I haven't decided when I am going to do the first fluid change interval... It will either be immediately or at 60,000 miles.
Anyways it is under warranty until 11/17/2009 so I have two years where I have to use OEM BMW fluid. Afterwards I might try out the Redline Fluid, only after a multiple fill/drain to clear the fluid.
I am planning on driving this car for a looong time to come, so maintenance is my main goal!
