In this video I walk you through how I install car mods in GTA 5 Story Mode on PC in 2026, step-by-step, the beginner-friendly way. I keep it simple: what files you actually need, where they go, and how to avoid the usual “it crashed after I added a car” situation. I also explain the two main types you’ll see on GTA5-Mods—add-on cars vs replace cars—so you don’t install the wrong one and waste time. I’m using the same core setup I recommend for most Story Mode modding: Script Hook V so your game can run scripts properly, and an Addon Vehicle Spawner so you can spawn add-on cars in-game without confusion. For the example, I link a Lamborghini Huracan Performante mod, but you can use literally any add-on car from the tag page and follow the same process. If you’re new, start slow, install one car at a time, and test your game after each change—this is the easiest way to stay “no errors” and actually enjoy the mods.
