All pillars that support the roof are lettered in order front to back. On a typical sedan pillars behind the front doors are B pillars and those behind the rear doors are C pillars.BTW - why is that called the "A pillar"?...have always wondered...
I’m about 50 car washes in, no damage.I've had two car washes say it is a no go and that it could cause damage. Is this true? I don't know. I never took the risk to find out elsewhere and handwash instead.
