Mod a Vehicle at a Car Mod Shop

To perform this objective, you need any vehicle that can be modified at Los Santos Customs or Benny’s original Motor Works.

If you were going to modify one of your cars or bikes, just do it. But if you don’t need to do it now, do the following: go to a car mod shop, steal the most expensive car nearby, drive it into a mod shop and repair if it’s necessary.

Then change the license plate using the cheapest option. After that, you can immediately sell the car. This daily objective will be completed when you leave a car mod shop.
