Texas has had a LOT of rain the last week or two, and I've been at a conference where my car sits on an outside lot. I can't feel anything wet on the headliner, interior carpet, seats, etc.
But the car smells like DEATH.

It's heinous. It's somewhere just worse than locker room mildew, and just short of decaying roadkill. The car will be undriveable if this gets worse! I left the windows down in my enclosed garage last night, but it does not seem to have helped.
Where do you go about looking for water or dead things in a W210?!

Thanks! Meantime, I guess I'll put a box of baking soda or something in there to try and soak up the stink a bit.
Cheers, John
