I purchased this 325i new in Oct. 2005 as a 2006 model. High on fun to drive meter but too many serious repairs. The car was great until about 75K miles. From 75k to 129k ignition coil failures, head bolt replacements, chipping paint, window motor failure, radio LED failure and sticky door handles. However I still love the car but not inclined to purchase another. I also had a 94 325 and a 97 525 which had less electronics but were more reliable.
Handling, smooth reving engine, excellent braking
Get rid of half the electronics and focus on durable drivetrain and suspension.
