You got good advice at first but seem to have ignored it.... now you will pay the price.

With water exposure the ABSOLUTE first thing you do is open it up, eleveate temperature and aerate. In the garage, all doors open, fan, space heater. Remove as much as you can. Seats, carpeting, etc.

if you do this immediately, you might avoid mold.

Now you have mold and will always have the smell until you replace the moldy carpets, padding, door panels, seat cushions, etc. I can guess that the carpet padding under the carpet you feel is probably still wet.

Bills for this run thousands.

If you do not have a garage or the ability, paying a few hundred to a professional would have been the plan,

Whats your VIN? Future owners will want to know....
