Info in other thread should guide you. Vibration/wobble has been evident in all F30 cars, worldwide. Cars with DHP (VSS and Adaptive M) will experience much less or no vibration and ALL F30 cars built after 11/2012 should be OK.
Test drive cars and find out for yourself. Not all F30's are a problem. You may get lucky and find a gem.
Trying to help.
