I've tried reinstalling the game, openIV, checking that I have the asi files installed, etc 

I've even sought out for articles relating to this such as this:

 Now he says the problem is either you installed it in an old patchday or you have not installed the asi files on openIV which I checked and I installed on the newest patchday, and i've installed the files, but nothing, all that changed is the original police cars stopped making sound when I turned on the siren (because of the els file I installed with the vehicle files).

Nothing I do seems to make any difference, I have tried literally everything, it has been months since I have been able to get it to work USING THE EXACT SAME METHOD I AM NOW

and yes I tried using lml

Because you did not install them in the correct dlc patch. And this shouldn't take months to solve, you could've tried to use different dlc patch.

 

Try to use patch24 or 25, and make sure the vehicle's name is the same as the vilinia vehicle's name.
