Broken vehicle model

Hey, so i had replaced the LSPD vehicles earlier today (with [ELS] LSPD Valor Pack (Reupload) 1.0.0, i know its a reupload and had bugs but i was prepared for that, or so i thought), unexpectedly one of them started crashing my game but that was fine, i replaced all the files with the ones i had in my backup and just got an another model (Los Santos Police Department Upgrade Pack 1.0.0). But alas the Police Cruiser 2 was completely broken up, textures all buggy and doors spinning instead of the wheels (which were missing) EXCEPT if i was further away from the vehicle, it would look fine from ~5 meters (16 feet) away. So i got my backup files as earlier, got a new model (Federal Signal Valor State Trooper Hellcat Charger because police2 was the only model affected so i thought it would be a good replacement) and just ported the livery by hand, but the problem still stayed as seen in this video, i dont really know what to do, honestly makes the game quite unplayable seeing a monstrosity like this around. Should i just nuke my mods folder and start over or what?
