100,000 km is a review point, not a fixed parts list
Two cars with the same mileage may differ in age, engine, use, and previous replacements. Start with the manufacturer's schedule and invoices, then add what inspection reveals. Do not buy a '100,000 km package' solely because of its name.
Build the service record first
- Identify the version. Year, engine, transmission, and market, not just the model name. Find its service guide.
- Gather what has already been done. Dates, mileage, fluid types, and parts. A clear invoice photograph is better than remembering 'we did the major service'.
- Match time and distance. Some items have an age limit or special operating conditions. Reaching a mileage figure alone does not make every job due.
- List complaints separately. A new noise, fluid loss, or harsh shifting needs diagnosis alongside scheduled maintenance, rather than disappearing inside the package.

Split the quotation into three groups
Replacement with a known due date
For example, oil, a filter, or an item with a documented interval for this engine. Ask to see the scheduled item and its previous service date. These examples are not replacement orders for every car.
Inspect, then decide
For example, brake, tire, and suspension components. Ask for their condition and reference limits rather than replacing them all because of the odometer reading.
Diagnosis or optional servicing
Cleaning, additives, and similar work are not automatically necessary. Ask what problem each item addresses and what evidence supports it.
A practical sheet for discussing the quotation
| Item | Question before approval |
|---|---|
| Timing belt or system | Does the engine use a belt or chain, and what does the manufacturer recommend for this version? |
| Transmission fluid | What transmission type, fluid specification, and service procedure are required? |
| Coolant | When was it changed, and are the specification and filling procedure correct? |
| Spark plugs | What is the correct part number and scheduled service life for this engine? |
| Brakes and tires | What measurement or visible defect justifies replacement? |

If the maintenance history is unknown
Do not invent an earlier service date or replace everything at once without assessment. Ask which critical items have unconfirmed service histories, and request written priorities: urgent safety work, documented overdue maintenance, then monitoring. Missing invoices do not prove that components were never replaced, but they reduce certainty.
Compare quotations only after making their scope consistent. A cheaper quotation may omit a fluid, filter, or procedure; a larger one may add optional work. Ask for parts and labor to be separated, with specifications and the offered warranty clearly stated.
After the work
Create a starting point for a new record: date, mileage, completed items, specifications, and upcoming due dates. Check fluid levels using the approved method and report any leak or warning appearing afterward. Do not wait until the next service to address a new symptom.
Questions to help you decide
Must every belt be replaced at 100,000 km?
Not as a general rule. Identify the belt type, manufacturer recommendation, age, and condition. An accessory belt differs from a timing belt.
Can I postpone an item because the car runs normally?
The absence of symptoms does not cancel scheduled maintenance that is due. Discuss postponement according to the component's function and service schedule, not feel alone.
