Custom identity and intent Establishes what is being customised and what the changes are intended to achieve.

Baseline and build lineage

Connects the custom configuration to its donor vehicle or original design.

Baseline departures

Record the reference configuration and separate deliberate alterations from repairs, replacement parts and restoration work.

Revision and reversibility

Tracks subsequent changes and the extent to which earlier configurations remain recoverable.

Configuration change consequences

What it is Filled

A custom car is a passenger vehicle deliberately and substantially altered in appearance to express an owner's or builder's preferences beyond its original or standard design, with possible accompanying performance or configuration changes.

In scope

  • Base-vehicle identity, build provenance and the boundary of the customised vehicle
  • Customisation intent, styling language and departures from the baseline configuration
  • Installed modifications and interactions among body, chassis, propulsion, controls and cabin
  • Evidence of build condition, functional integration and suitability for intended use
  • Modification-specific maintenance, documentation and future alteration constraints

Out of scope

  • General car construction and operation already covered by a broader car model
  • The customising workshop, its business processes and its personnel
  • Standalone models of engines, tyres, suspension components and other constituent parts
  • Car shows, races and custom-car communities as events or social organisations
  • Jurisdiction-wide vehicle approval rules as independent regulatory models

Why it exists Filled

Enable an AI agent to recognise a custom car, understand its departures from a base vehicle or original design, assess its documented condition and identify prerequisites for proposed use or further modification.

Distinguishing features Filled

  • Documented changes to a base vehicle or original design support a customisation intent; ownership or an unusual paint colour alone does not establish the boundary.
  • A restoration seeks a stated historical configuration, whereas a custom build intentionally departs from its baseline; a vehicle can contain both kinds of work.
  • A production trim or factory option package is distinguished from an individually specified custom configuration by the provenance and scope of its changes.
  • Performance tuning and hot-rodding can overlap with customisation, but neither increased output nor a particular powertrain is assumed to be required.
  • The model describes a category of cars; an individual build supplies the actual donor identity, modification history and condition evidence.

What robots and AI may and may not do Filled

Must not

  • Help modify a car so that it no longer meets road safety or emissions rules for road use.
  • Disable or tamper with safety systems such as brakes, airbags or lights.
  • Misrepresent a modified car's identity, mileage or history to a buyer.
  • Alter or remove vehicle identification numbers.

Only with a human decision

  • Registering a heavily modified car for road use requires human involvement.
  • Reviewing modification disclosures before a custom car is sold requires human involvement.

May

  • Describe a custom car's modifications and history from its owner's records or visible features.
  • Check whether a modification needs approval or inspection under the rules of a stated jurisdiction.

Moral aspects Filled

  • Modifications can make cars dangerous to occupants and other road users.
  • Custom building is a craft and form of expression that many communities value.

Who is affected

  • Drivers and passengers
  • Other road users
  • Buyers

Owners Filled

Steward

The registered keeper; vehicle authorities approve modifications for road use.

Master systems

  • National or regional vehicle register

  • Wikidata: Q1146195 (https://www.wikidata.org/wiki/Q1146195)

Direct properties required Filled

  • Baseline vehicle or design: Identified production vehicle, donor configuration or documented original design; unknown permitted
  • Customisation intent: Appearance, performance, comfort, accessibility, exhibition, mixed or other stated intent
  • Modification coverage: Bodywork, finish, chassis, suspension, wheels and tyres, propulsion, braking, electrical systems, controls or cabin; multiple values allowed

  • Ride height and ground clearance: Millimetres at named reference points, with load and suspension setting recorded
  • Wheel and tyre fitment envelope: Wheel diameter and width, offset in millimetres, tyre designation and measured clearance in millimetres under stated steering and suspension conditions
  • Mass and axle loading: Kilograms for total and axle loads, with fluids, occupants and equipment stated
  • Modification evidence: Build records, drawings, component identifiers, photographs, inspection reports and test results linked to a configuration
  • Use eligibility evidence: Unassessed, evidence incomplete, documented for a named use and jurisdiction, restricted or unknown

Recognition required Filled

  • Bodywork, paint, wheels or ride height clearly differ from the factory model.
  • Common signs include chopped roofs, custom paintwork, altered grilles or exposed engines.
  • Registration records settle the original model and identity.

Capabilities and actions required Filled

  • Compare a build with its baseline and explain what makes it custom.
  • Trace a proposed modification to affected systems and required checks.
  • Inspect custom bodywork, installation interfaces and clearance-sensitive components.
  • Evaluate whether documented evidence supports a proposed use of the current configuration.
  • Plan maintenance and replacement around bespoke parts and altered access.
  • Record a revision while preserving the provenance and verification history of earlier configurations.

Hazards and failure modes required Filled

  • Poorly engineered modifications can cause loss of control or structural failure.
  • Engine and exhaust changes can raise emissions and noise beyond legal limits.

Standards and interfaces required Filled

  • UN Regulations annexed to the 1958 Agreement on vehicle approvals, United Nations Economic Commission for Europe (UNECE).

Context of use required Filled

  • Custom cars are encountered at exhibitions, enthusiast gatherings and workshops, and some are used for ordinary road travel.
  • Their altered bodywork, paint, interiors or mechanical systems express individual preferences and may support display, recreation or specialised performance.
  • Assessment depends on identifying the base vehicle and documenting modifications that affect condition, operation and permitted use.

Open questions

  • Does the registry use custom car broadly for deliberately customised cars or narrowly for a particular historical body-styling tradition?
  • What minimum extent or intent of modification distinguishes a custom car from a car with ordinary accessories or cosmetic personalisation?
  • How should factory bespoke commissions, coachbuilt cars, kit cars and scratch-built cars relate to this entry?
  • Which existing Vercy car, modified-vehicle or world models should supply shared properties and prevent duplicate conceptual coverage?
  • Which authoritative sources and jurisdiction-specific requirements should support later findings about construction, inspection and permitted operation?
