Again, this is only my 0.02 cents
It wasn't my M3 that had the windshield problem but my very first car back in 1999 that had a cracked windshield. I was a student with minimum income and I chose to go cheap on non-OEM windshield. 2 months later I had a leak which cost $6k to fix on a car that was worth not more than $9k. Learned my lesson the hard way.
