Welcome to GTA5-Mods.com

Great work! One bug I found was changing the window tint to any level also darkened the headlights too. For some reason this happens with lots of car mods out there but not all, I don't get why.

@BloodyRonin Put all your mods files out of the gta library and see if it crashes even if this is your only mod installed. If it does maybe your game version is too old, or the car is in fact incompatible ( I will try tomorrow if it is likely incompatibility)
If it does not crash when it is your only add-on it is very likely that you have too many HQ addons installed, try deleting the ones you don't like using. Especially those that take 2-300 MBs

@Spaarks7 I think he is answering to the "your mom" license plate.
It is a great mod, I noticed 2 things so far that you could improve, one is a real, modifiable license plate, and the other is that the if you try to set window tint, all the windows and the headlights become fully black. Other than that it is great

When I try to spawn the add-on version with 2016rs7 code, it says it has been spawned but the vehicle does not appear. It has happened with some other cars in the past but this one is too good to let go.
I am currently running a pirated version (though I own the cd version for xbox and pc too, i just did not want to install it yet.). Maybe the pirated version is the problem?
