I'm looking to buy a used car (2017 Prius Prime - leather interior) and the dealership informed me that there was a faint odor of smoke in the vehicle. They left an oxide machine in the vehicle over night and now claim that it's fine.
Do these oxide machines "permanently" remove smoke odors? I'm nervous about buying the vehicle and having smoke odors show up later. At the same time though, it's unclear where the odor came from (perhaps a person test driving?)
The dealership isn't sure how long the smell was present.
How reliable are oxide machines? Is it ever possible to remove smoke smell? The vehicle seats are leather if that makes any difference.
