# Parts & Cargo

> CZ Autoz / Callatic vehicles use vanilla DayZ car parts and removable doors/wheels, plus in-vehicle cargo storage — what each vehicle needs to run and how parts persist in the economy.

CZ Autoz vehicles are built to behave like vanilla DayZ cars — they use **standard parts**, their doors and wheels are removable items, and every model carries cargo.

## What a vehicle needs to run

The vehicles use **vanilla** DayZ car parts — there is nothing custom to add to your economy:

<CardGroup cols={2}>
  <Card title="Car Battery" icon="car-battery">
    Required to start and to power lights.
  </Card>

  <Card title="Spark Plug" icon="bolt">
    Required for the engine to run.
  </Card>

  <Card title="Radiator" icon="temperature-half">
    Where applicable, to prevent overheating.
  </Card>

  <Card title="Wheels" icon="circle-dot">
    Each vehicle's own wheels (a separate item per model).
  </Card>
</CardGroup>

<Note>
  Because the parts are vanilla, repairs work exactly as players already expect. The only mod-specific classnames are the **vehicle**, its **wheels** and its **doors**.
</Note>

## Doors & wheels as items

Doors and wheels come **attached** to the vehicle, but they are real items — knock one off (or remove it) and it persists in the world as a spare. On colour-variant vehicles the door panels are **per-colour**, so the spare keeps the right paint (e.g. `ShelbySuperSnake19_Driver_BlackRed`).

The naming is predictable: `<Vehicle>_Driver`, `_CoDriver`, `_Hood`, `_Trunk`, `_Wheel` (some models add `_Cargo1`, `_Spoiler`, numbered wheels or per-colour wheels).

<Warning>
  You only need door/wheel entries in `types.xml` if you want **loose spare parts** to spawn or persist in the central economy. They are not required for the vehicle itself to work. See the worked example on [types.xml & events.xml](/vehicles/types-events-xml).
</Warning>

## Cargo storage

Every vehicle carries **in-vehicle cargo**. A few models add more:

* **Vans Pack — Mercedes Sprinter** — the liveried delivery variants (DHL, DPD, Amazon, Parcelforce, FedEx, Yodel, British Gas) carry **interior cargo shelving** for extra capacity.
* **Armoured Pack — HEMTT Cargo / Box** — the cargo and box bodies are built around hauling.

<Tip>
  Cargo lives on the vehicle, so it persists with the vehicle across restarts like any DayZ car inventory.
