Have started to notice when i first get in the car if i have been out for a decent time i.e overnight that there is a slightly fishy smell (i know) theres defo nothing under seats or anything like that as no food is allowed inside lol. Once i open a window and let the air circulate it goes away. My missus says its something to do with the leather interior as she says leather hand bags can emit the same smell. Is this correct? How do i sort it?
