Is there a limit on how many custom cars you can add to a server?

I am asking because i was working on making a server for me and a friend and i added 150+ custom cars,and when i go in my server to test at least 2/3 of them won’t even spawn with my trainer i am using.

Is there a limit?

Or is it something on my end? If it is i will make another post in support to fix it.
