Congratulations on your odor disappearing! I can only hope...

So far, I have done nothing but remove the filter and floor mats. How necessary are they. I seldom drive in dusty conditions.

Speaking of cabin filters, I have owned Fords, Oldsmobile, Chevy, Dodge, Plymouth and even and AMC and had never heard of them. The crossfire is the newest vehicle that I have purchased and did not expect it to have an odor.
