I recently bought a 2007 Z4M coupe.
Had an oil change last year (among other things) before winter.
This time around I had a lot of maintenance work done, more than anticipated, but am grateful for the piece of mind I have in having it all done.
Kudos to Jacqueline Brennan for being so patient, thorough, knowledgeable and keeping me so well informed.
Thanks also to the techs - much appreciated.
