How to make Roman's taxi spawn in traffic

If you've ever played GTA IV, you'll probably know that Roman's taxis are not available after you unlock Algonquin safehouse. I'm sure I'm not the only one who miss them, since it's the most iconic vehicle in the game. But did you know you can bring 'em back, by simply editing some letters in the game files using Notepad? Here's how!
No other mods/scripts required.

1. Go to the main game folder.

• Right-click the game, select Properties -> Local Files -> Browse

• Then go to GTAIV -> common -> data

• You'll need to edit cargrp.dat, vehicles.ide, and carcols.dat(Optional) by using Notepad.
  Just in case, create backup first!

2. Editing cargrp.dat

• Open cargrp.dat by using Notepad. This file is about the vehicles that certain people groups will drive.
  For example,
  

  police, police2, polpatriot, noose, predator, pstockade, nstockade, fbi
  # POPCYCLE_GROUP_COPS

  This means that the following car models(police1, police2...) will be driven by police npcs.

• Choose any people group you want and add the car's model name in the list. (I recommend GROUP_TAXI and GROUP_BROOKLYN, because Roman's taxi is a kind of taxi, and the cab depot is in Broker, which is Brooklyn in real life.)
  The model name of Roman's taxi is 'rom'.

3. Editing vehicles.ide

• Open vehicles.ide through Notepad. This file is obviously about vehicles, such as player animations in vehicles, what engine sound the vehicles will use, how much will the vehicle spawn, dirt level and so on. This might look complicated, but thankfully all we have to do is change two certain values of one specific vehicle.

• Search for 'rom', the file name of Roman's taxi and change the values in the circles. The original value of your file will be 1, 0. My file is already modded, so you can ignore the difference.
  
  • The number in the red circle is about the vehicle density, and max value is 100. The bigger the number is, the higher the chance of spawn will get .
  • The number in the green circle is means how much can the vehicle spawn at once. the default value of most vehicles is 999.
  I recommend 20~40 for the density and 999 for the spawn limit. It's your choice, just don't set any value to 0.

4. Editing carcols.dat (Optional)

• Now, you can see Roman's taxi on the streets! But they will spawn in various colors, which somewhat doesn't feel right. Roman's taxis should be black, don't they? Here's the way to fix that.

• Open carcols.dat via Notepad and search for 'rom'. The reason why Roman's taxi spawns in various colors is because it's pre-set to in this file. (I don't know why the devs even bothered to do this, since the car never spawns in traffic in vanilla game.)

• If you want the black-and-gray ones just like the ones you normally drive in story missions, add or replace the values to '0,1,1'.
  
  • The first value is about main color of the vehicle, and 0 means black.
  • The second value is about secondary color of the vehicle(In this case, the left fender), and 1 means black poly.
  • The third value is about specular color of the vehicle.

• If you want the rare, unobtainable full-black variant that you drive in 'The Cousins Bellic', also add '0,0,1'

5. Done!

• Congratulations! Now you can see Bellic Enterprises actually running throughout Liberty City. Roman will thank you!

• By using same method, you can also make Romero spawn too!

THANKYOU this is my first mod to the game :D

[BigWalt]

It wouldnt work for me. I followed all the steps anyone know why?

[gunitmob411]

I mean... the apartment burned down and Roman loses everything but sure

[RAK]

Correct me if I'm wrong but isn't the Algonquin section of the game after the company and your apartment gets burned down? Wouldn't make much sense considering everything inside was destroyed

[StarDroid877]

Thank you so much, this is one of the best cars in the game and it makes it look like Roman actually has an operating Taxi business now that they spawn in the streets!

[Wanoo]

If only it could be called... The Bellic Taxi company does not disappear anywhere even after beating the game.

It is based on Esperanto, but the taxi got its own exterior parts and is waaaay faster.

just steal an Esperanto, same car
