How do I get NPC to drive modified cars?

[Estdo]

In GTA V you will see some NPCs driving a modified Ruiner, Turismo, etc. So I wanted an NPC to drive a Coquette that a tuned to resemble a Corvette ZR7, How do I do that?

In that file you will find all the modded/upgraded vehicles that spawn around Los Santos.

There are various sections headed:

    <Item type="CAmbientModelSet">

that define the vehicles that spawn at certain locations. It should be pretty easy to figure out which one you want to replace. Search for '<Name>RUINER</Name>' etc to find the vehicle you want to replace & then change it's name, body colour & upgrades to the values for your modded Coquette.
Note: There are 4 modded Ruiners in there. Use the bodycolour codes:

          <Name>RUINER</Name>
          <Variations type="CAmbientVehicleModelVariations">
            <BodyColour1 value="54" /> primary colour
            <BodyColour2 value="81" /> secondary colour
            <BodyColour3 value="37" /> pearlescent colour
            <BodyColour4 value="156" /> wheels colour

refering to this chart to tell which is which

Note: 'BodyColour1/2/3/4' = primary/secondary/pearlescent/wheels etc may vary on modded vehicles at the mod authors discretion. Secondary paints the wheels on some cars for example.

Those examples above also spawn on the streets in certain locations. Not just outside LS Customs.

Note: ModIndex value's you enter are offset by 1 - ie 0 = 1 - ie You put 5 in the 'ModIndex value=' line to choose the 6th upgrade listed in trainer etc (liveries work similar I believe).

Example:

              <Item>
                <ModType>VMT_SPOILER</ModType>
                <ModIndex value="7" />
              </Item>

^This would choose the 8th Spoiler in the trainer list.

Extra:

<ModKit value="0" /> -- Chosen Upgrades are applied 

<ModKit value="1" /> -- Upgrades are disabled & vehicle is standard. 

^Something to be aware of if you find yourself unable to upgrade a vehicle etc.

That should be most of what you need to get started. Any questions/problems & I'll help you out
