Selling your car: why the service history sets the price

Buyers do not pay for your word

Every seller says the car was well maintained. Buyers have learned to ignore the sentence and look for evidence, so the price conversation ends up being about what can be proven.

The three things a careful buyer checks first:

1. The timing belt — done or not, and can you show the invoice.
2. The oil change history — regular, or two gaps of 40,000 km.
3. The last roadworthiness report — what came up, what was fixed.

Assemble the file before the ad goes live

Do this in one sitting, before the first message arrives:

• Invoices in date order, each showing mileage and work.
• The last roadworthiness report.
• The registration document in your name, and the certificate of administrative status.
• A note of what is due next, with dates. Telling a buyer "the belt is due in 2028" reads as confidence, not as a warning.

If parts of the record are missing, our guide to rebuilding a lost service history covers how to get it back from garages and invoices.

Write the ad with specifics

Vague ads attract hagglers. Replace "well maintained" with:

Oil change at 128,400 km in March 2026 (invoice available). Timing belt replaced at 110,000 km with water pump. Roadworthiness test passed June 2026, no faults. Four tyres fitted in 2025.

That paragraph does the negotiation for you, because there is nothing left to assume.

What not to do

• Do not reset expectations at the viewing. Surprises discovered in person cost more than the same facts written in the ad.
• Do not hand over the original invoices. Give copies; keep the originals until the sale is complete.
• Do not skip the administrative certificate. A buyer who cannot register the car will walk away, however good the mechanicals are.

Keep the record while you own the car, not the week you sell

Assembling three years of history in an afternoon is painful, and things go missing. Logging each service when it happens takes seconds, and the file is then always ready.

That is what Autofy does in the background: every service recorded with its date, mileage and document, per vehicle.

Frequently asked questions

Does a service history really raise the price? It mostly protects it. Buyers discount what they cannot verify, so the file removes the argument rather than adding a premium.

What should I put in the ad? Mileage, the date of the last service, the timing belt status, the current roadworthiness test, and that invoices are available. Specifics attract serious buyers.

Should I service the car before selling? A recent oil change with an invoice is usually worth more than its cost. Large repairs rarely pay for themselves — it is often better to price them in and say so.
