Before anything, I did make screenshots, but PhotoBucket no longer shares the pictures unless you pay them, which I am not intending to do.
If you like I could mail you the screenshots?
In-Depth explanation:
The new Sheriff2 vehicle is a Sheriff Interceptor car, which replaces the Sheriff Transport.
Annoyingly this car seems to be using the FBI2 handling, but a sports car with a SUV handling?
Thus, I did this:
Added and replaced new SHERIFF2*.YTD and SHERIFF2*YFT files to GTAv\Update\x64\DLCPacks\Patchday3NG\DLC.RPF\x64\Levels\GTA5\VEHICLES.RPF
Added newly created SHERIFF2 handling in GTAv\Update\UPDATE.RPF\Common\Data\HANDLING.META
Altered the line <handlingId>FBI2</handlingId> into <handlingId>sheriff2</handlingId> in GTAv\Common.RPF\Data\Levels\GTA5\VEHICLES/META
Still, somehow Sheriff2 uses a transport/SUV handling (quite bloody noticable).
Do you need the HANDLING.META info, the VEHICLES.META information/files?
