Have you tried shampooing the seats, carpet, cleaning all the plastics down? Seems I end up doing that on every used car I buy.
Yes this. I use my old Bissell big green with hot tap water mixed with laundry det to clean EVERYTHING that is cloth. A seat may LOOK clean but wait till you see what the cleaner sucks out. Even when the cleaner is pulling nice clean solution out of the upholstery- wait 10 min and clean again. The deep junk wicks toward the surface and youll be sucking up brown dirty solution allllll over again. Ive spent over 3 hours on a compact car doing it all. Nice and clean afterward. When done place a heater in there with windows cracked to vent and all will be good.
