This is a quick and hopefully helpful tutorial that will help new people know how to add custom cars to their game focusing mainly on the Police cars, but it's the same steps for other cars. I won't be adding links for the obvious reason that I don't want to push any copyright infringement linking where I should not.

When you download a pack, it will be as a compressed archive .zip .rar .7z whatever, you will need a program to open these files. Windows Explorer on Windows 7 computers will open most .zip files, but for .rar or .7z you will need better programs. I recommend WinRAR which you can google to find, and install.

Next open up the folder and extract it. I recommend putting it in a folder you will easily be able to find, and I also recommend putting each different car in to a different folder as some will have the same .wft .wtd file names causing overwrites.

Next you will need to get OpenIV or SparkIV, again google is our dear and glorious leader for this. for the rest of the tutorial I will assume that you have SparkIV.

!!!IMPORTANT!!!!

Don't skip this step. Manually browse to your GTAIV folder and select the cdimages folder copy and paste it in to a separate folder for backup purposes!!! If you fail to comply with this step then if you wish to revert back to the original cars you will have to remove the game completely and start again!!

Open up SparkIV and then click Browse, give this some time as it attempts to find your GTA IV folder. When it refresh's go through the tree to GTAIV -> pc -> models -> cdimages then on the right side of the window double click vehicles.img to open it.

police.wft + police.wtd is your first police car in selection

police2.wft + police2.wtd is a second car.

polpatriot.wft + polpatriot.wtf is a paddy wagon.

pstockade.wft + pstockade.wtd is a paddy wagon.

noose.wft + noose.wtd is a car.

nstockade.wft + nstockade.wtd is a tactical unit truck.

fbi.wft + fbi.wtd is another car.

It is important to assign a car to a car, and a truck to a truck. Most mods will tell you what they are designed for.

Now what you have to do is go to the downloaded cars that you have and change the .wft and .wtd to one of the ones above to be recognized by LCPDFR. You can only have one car under each name, so don't have two of police and one police2. (honnestly I have not tryed adding cars under different names, but from my limited knowledge if they do show up in game, and are spawnable, I don't believe that LCPDFR will let you choose one when you come on duty....feel free to experement and play at your own expense, just hope you have a backup, also I am not sure if you can modify it so that LCPDFR can pick it up, again I am not wanting to mess with my system.)

Then click import and import both the .wft and .wtd files for each car you have and then click save.

Now you have added the cars in to the game. Enjoy them.

Sorry that this tutorial is not complete with screen shots, I do plan on including them later, but it's late, and I need to nap before work tonight. I hope this helps many people, and if there are things that I have missed please let me know and I will fix it.

EDIT: 06/03/2012: Added the other cars, and their descriptions.
