Yup,
 
First you need LSPDFR (of course), Ultimate Backup (to make the cars spawn as backup) and Jurisdictions+ (To make them spawn at right place).
 
i add all the cars as addon, and name them, for example, a Tahoe for Vespucci Beach PD, i name it VBTahoe, then you need to edit the carvariations.meta and vehicles.meta, in order to make the game "know" he have to add them and how they behave (siren, how they drive ...). Tutorial avaiable on Youtube etc ... it's the classic way to install add on cars.
 
And next, you have to edit files in :
D:\Steam\steamapps\common\Grand Theft Auto V\lspdfr\data\custom
Here you have all the agencies you have with Jurisdiction+, and you need to add your new car to the agency you want him, i stay with Vespucci Beach, edit agency_vppd, and add in vehicles <Vehicle chance="50">VBTahoe</Vehicle>, change the vehicles chance if you have more than one vehicle.
 
Then go to :
D:\Steam\steamapps\common\Grand Theft Auto V\Plugins\LSPDFR\UltimateBackup
Edit DefaultRegions if it's about :
      - LosSantosCity
      - LosSantosCounty
      - BlaineCounty
      - NorthYankton
 
And CustomRegions for all the others.
 
Same as before, you scroll to the agency you want, and change the vehicle name and vehicle chance. You can also in these files customize wich car you want as local backup, state backup, K9 ....
