Genuine, OEM and aftermarket parts: comparing a repair quote

Parts descriptions can be ambiguous. Ask for the manufacturer, part number, specification and condition rather than relying on a label such as original or premium. A clear written description helps you understand what the garage is actually proposing to install.

Compatibility and warranty matter together

Ask why the proposed part is suitable for your model and whether sensors, software or calibration affect installation. Confirm whether it is new, reconditioned or used and who handles a warranty claim. Keep the quoted part details on the invoice. A familiar brand name alone does not confirm that a particular part matches your vehicle.

What the inspection or service should clarify

Agree these points with the garage before booking. A list of possible checks is not a diagnosis of your car, and the quoted scope should state which are included.

• Manufacturer schedule and previous service record
• Engine oil and filter if applicable
• Brake, tyre, fluid and suspension inspections
• Written findings and separately authorised repairs

What changes the quote?

Ask for a written HKD quote identifying the vehicle, parts, labour and assessment fee. Compare the same scope across garages; a package name or starting price alone does not show what will be done.

• Engine/powertrain and approved oil specification
• Filters, consumables and labour listed separately
• Inspection only versus parts actually replaced

Prepare useful information

Send the model year, powertrain, mileage and service history. Describe the exact warning or symptom and when it happens. Include whether the car can be driven and where it is parked; confirm access and transport separately from the repair price.

• When was the last service and what was replaced?
• Are there warnings, leaks or changes in how the car drives?

Before authorising the work

Confirm whether the quotation is fixed or subject to inspection, what is excluded, when parts are expected and how extra work is approved. Ask for written warranty terms and the follow-up process if a symptom remains. Keep the invoice and job sheet with the maintenance record.
