i bet i have the same smell... i go through air fresheners faster then anything. its like a strong vinegarish armpit smell. my car only has 7700 miles so its barely been driven but its had this smell from the start. When the A/C is turned on and u get that warm air drawn in at first.. i have to cover my nose. I have no help.. i am in the same boat sir. i hope the cabin air filter fixes this.
