Hello people! Before getting started to I want to suggest that
you should make a backup of your current game if you are going to mod anything in the game, because you might mess it up and need to replace some files fast.
Every vehicle mod that is going to be shared here should be
only the .dff and .txd files, so it won't affect the basic stats of the game.
I found some interesting models for the FBI Rancher, Vice Squad Cheetah and Comet, to be more exact, the real life models of these cars: Chevrolet Suburban 2500 1986, Ferrari Testarossa 1986 from Miami Vice and Porsche 911 Turbo 1982, and i think there is also a Sabre Turbo HD model, with two colors
In order to change the models you will need Txdworkshop or other program that you might find handy, but i am using Txdworkshop. Txdworkshop is free and can be found on gta modding sites:
Here is a post model if you want to post your vehicle models:
In order to install just the .dff and .txd files, you might want to hit the download button from the site and download the archived files. Donwloading the automatic installer and installing it, may change other game files.
Here is a video how to use Txdworkshop to replace models in game: (coming with a video later, after i finish editing it, meanwhile you might find some tutorials online)
