This is a LAPD livery for the electric bmw i3, just like the one the lapd uses. They purchased a hundred of these a few years back for patrolling the community.
This is only a livery NOT a model. If you want to download the model, you can find it here: https://www.gta5-mods.com/vehicles/metropolitan-police-2018-bmw-i3
*download the livery and model
*use Open IV to open one of the .ytd files (whichever model you wanna use) and replace the current livery with the one provided
