Los Santos Customs Achievement
Los Santos Customs10
Fully mod a vehicle.
After the story mission, "Father/Son," you can begin customizing your vehicles at the Los Santos Customs shops. These shops will be marked as a spray paint can on your map. Since each car varies from mods and price tags, there is no set vehicle to use for this achievement. Just make sure you purchase one of every upgrade from each section in the customize menu when inside the shop. Depending on your vehicle and which mod suits your taste, you will need to save upwards to at least $40,000 to fully mod your car.
Take note that the achievement only unlocks once you exit Los Santos Customs. Many people are also overlooking the fact that you need to buy one of each wheel accessory: Custom Tires, Bulletproof Tires & Smoke Tires; and the Chrome finish in addition to any other regular respray (Classic, Matte, Metallic).
