I just called the dealer and he brought up a very valid point about 19" wheels. The Tri-state area roads SUCK. So one bad pothole = bye bye rims. He also mentioned that ordering the 19" would bring about the strong possibility of my order being delayed since a previous customer did the same and his car still hasn't been delivered (no further details given on that). So, I guess I DO care about delays
It still feels like I'm reluctantly sticking with the 18s
