A855 - 5 Speed

Part of the letter sent today:
SUBJECT: A833 5 SPEED
You know as a 855 happy owner I'm following this, mostly on FBBO because, well, I drive a B-Body.
This may seem/be insignificant, but when writing a "legal document" some errors could be fatal. You either made a mistake in the line I quoted or on your letter.
The 5 speed is a 855, NOT a 833.
Just trying to help.
