AC SMELL- can it be avoided?

[dvl57]

I got the smell out by leaving my blower on w/o the a/c function everytime for 2 mins prior to shutting off the engine. the purpose is to blow out all the cold a/c air prior to shutting it down. this helps eliminate any smell.
my 08 doesn't turn on & automatically blow the a/c (as what you describe in your 07)
my brother's bmw m5 does that...automatically cools the cabin down when it's too hot.
