My wife and I were looking for another mustang gt for her a few weeks back, and we happened to be in Beaverton and we saw a mustang at Beaverton Mercedes.
Had one salesman look at my gun while I was in the lobby waiting for the paperwork and he just kinda chuckled.
Then the lady salesman that sold us the car and had went on a test drive with us mentioned to me that she hadn't noticed my gun but only became aware of it because I`m guessing that the other salesman that saw it told her about it, she said that they prefer anyone carrying a weapon leave it in the trunk of the car.
But she wasn't worried.
"Prefer" and "require" are two separate animals.
