I want to buy a model with a realistic car that has some animation on it but I can’t find one with a commercial license, what I found on sketchfab the ones who are well done and realistic with animation do not have a commercial license.
CGTrader may be of some help - offers a good amount of high quality models (some a bit pricey, but usually worth the quality / support.)
But regardless the marketplace - most likely you can get a valid commercial license only on models without car manufacturer branding, otherwise may be getting in some trouble down the road.
The licenses are not clear…
