Did you write
anywhere on the multiple papers they had you sign:
"Bumper damaged and scratched upon delivery"
So simple, so easy- they cannot prevent you from doing this. All it does is DOCUMENT THE DAMAGE EXISTS. No need to demand they fix it or agree to fix it...just document it. Take the page, turn is sideways, down the side, in between the lines...whereever... just get it in writing at the time the deal closed....
Tomorrow, or the day after, or whenever, you then proceed to make someone fix it! You didn't need to get them, to agree to fix it- just that it was damaged and it was not acceptable to YOU. That you were taking the car with that caveat...
Instead you got into a pointless pissing match with idiots.
BMWNA will do NOTHING. Mark my word. Sorry. They will point you to the dealer, say "work it out with them" and "we are not responsible for dealer damage" or "the dealer tells us there was no damage"
Finally, you gave them too much information- they knew you had no choice.
Really sorry to hear about this- I know it is frustrating. Maybe look at it this way: You've had your
first minor scratch ...AND it is
neither your fault nor your wifes!!!
Enjoy it- great car
