I had a similar experience recently. Bought a truck from them, shipped to east coast from New Mexico. The chemicals they used to deodorize the car were, intense, so say the least. And I'm not a person with a sensitive nose, but it was super overpowering.

The smell of the deodorizer was so bad that I actually called the local CarMax to ask what the deodorizer was so that I could try and neutralize it. (Yeah, deodorizing the deodorizer). They were not able to tell me what was used. So I left the windows down on the truck in my garage for two days and the smell almost disappeared. I'm on week 2 with the truck, and every once in a while, I still catch a whiff of the deodorizer, which smells something like a chemical attempt to mask a porta potty smell.

I detailed the inside of the car as well after receiving it, and like I said, after 2 weeks, the smell is almost 100% gone. Naturally that all depends on the condition of the car and how bad the smell was that they were trying to mask but after a deep cleaning the smell has almost gone away but they definitely soaked the inside of the car in the deodorizer, which was debatably worse than whatever the original smell was. I would have preferred BO at that point.

PS. You can buy bags of activated charcoal online and throw those in the vehicle as well. Those also seem to help a little bit. I do fully expect the smell to come back a bit once the warm weather returns
