So, to start, No. Cars fresh off of the factory floor do not come with a ceramic coating. This is largely due to the application being cost and labor-intensive when blown up over a large scale, as you would get with vehicle manufacturing.
We may be a bit biased on this topic, but it is something that we encourage car owners to get if they want the extra protection and peace of mind that a ceramic coating brings. Especially as it makes your car more resistant to UV damage, scuffs, nicks, dirt, and other factors.
I hope that this helps
