i tried sapwning the new cars from GTA online with simple trainer and it show me the name of them but when i press spawn it saying "inviled model" i know it happens always with new car and i need to wait few weeks until it works in singleplayer... but there is anythink i can do to check them now?

YES!!
Nice

@ikt with the config the game infinity loading and without its crashing

Yestarday i installed a previous version of gta and played with mods,then i wanted to install new car mods,so i Opened OpenIV ,and when im opening GTA with openiv its infinate loading,and when im removing only OpenIV file (OpenIV.asi)
the mods are not working

@FoxtrotDelta oh ok ty lol

My OpenIv updates automatically,what should i do

Nice!
Good luck

@Reyser yes but i downloaded this pack
https://www.gta5-mods.com/vehicles/ferrari-458-spider-2013-add-on-tuning-livery
and the spider version tuning worked , i took the code from the spider and put on the coupe
and removed the spide because i dont use it so if it worked on the spider why wouldnt it work on the coupe

so i know that you need to change the numbers in this line:

<kitName>123123118_yFe458i1_modkit</kitName>
<id value="123123118" />

when you cant tune the car
so why did i change it to something that i know he is not taken and it still no work?
do i need to change another lines?
