Selling a car: which service records to show
What service records should I show when I sell my car?
Show a dated list of every service with the mileage at the time, the receipts behind it, proof that open safety recalls were fixed, and anything that explains a big job. Buyers are told to ask for exactly this: the FTC's used-car tips say to ask for the car's maintenance record[1], and NHTSA tells buyers to compare the odometer with the mileage on those records[2].
Why buyers ask for them
- To check the mileage. NHTSA's advice for spotting odometer fraud is to compare the odometer with the mileage on the car's maintenance or inspection records, and to look for oil-change stickers[2]. A steady run of dated services at rising mileages helps show the reading is real.
- Because a history report doesn't cover it. The FTC says a vehicle history report may list accidents and flood damage, but typically won't list mechanical problems[3]. Service records fill that gap.
- To ask a mechanic. The FTC tells buyers to have an independent mechanic inspect the car[3]. A mechanic who can see what was done, and when, can tell what's due next.
What to put in the folder
- A one-page summary, in date order: date, odometer reading, what was done, who did it. A printable log works.
- Receipts or invoices for each line, oldest first. For work you did yourself, the parts receipt with the date and mileage written on it.
- The regular services: oil and filter changes, tire rotations, brakes, fluids, filters. How often each one is due, with sources, is on the maintenance schedule page.
- The big scheduled jobs your owner's manual lists for the car's mileage, if they've been done.
- Tires: the purchase receipt. NHTSA notes that a car showing 20,000 miles or less should still have its original tires[2], so the tire history is part of the mileage story too.
- Recall repairs: the dealer's invoice for each one (see below).
- Inspection reports and any written estimates you were given, even for work you didn't do.
Check for open recalls first
Enter the 17-character VIN (lower left of the windshield, or on the registration card) at nhtsa.gov/recalls. It shows unrepaired safety recalls for that car, or "0 unrepaired recalls associated with this VIN"[4]. Two limits: it doesn't show recalls more than 15 years old (unless the manufacturer covers more), and recently announced recalls may not have all their VINs listed yet[4]. Recall repairs are free at a dealer for the brand[4], so fix anything open before you list the car and add the invoice to the folder.
The odometer reading
In the US, the seller has to disclose the mileage when ownership is transferred[2]. In 2026 that applies to model year 2011 and newer cars, which stay covered until they're 20 years old; model year 2010 and older cars, and vehicles with a gross vehicle weight rating over 16,000 lb, are exempt[5]. Write the reading down when you hand over the keys, and make sure it fits the last service in your records.
If some records are missing
- Ask the shop or dealer that did most of the work. The FTC's tips send buyers there when an owner has no copies[1], so the shop may well have them for you too.
- Look for oil-change stickers on the windshield or door frame and in the glovebox[2], and for card or bank statements that show the shop and date.
- Don't fill gaps from memory. A short note saying "no record from 2021 to 2022" is more convincing than a guessed entry.
Before you hand anything over
- Give copies; keep the originals until the sale is final.
- Cover your address, phone number and card digits on the copies.
- If your records are in an app, export them to a file the buyer can open without the app.
We make Wrenchy, an iPhone service log. It exports the whole history as a CSV file (vehicle, service, date, odometer, cost and notes), which opens in any spreadsheet and prints as the summary page above. It doesn't attach receipt photos to services, so the receipts still go in the folder. Other apps compared.
Questions
Does a vehicle history report replace service records?
No. The FTC says a vehicle history report may list accidents and flood damage, but typically won't list mechanical problems, and isn't a substitute for an inspection. Your own records show what was maintained and when, which a report usually can't.
Do I have to write the mileage down when I sell?
In the US, yes, for most cars: federal rules require the seller to disclose the odometer reading when ownership is transferred. In 2026 that covers model year 2011 and newer cars (they're exempt once they're 20 years old) and not model year 2010 and older. Vehicles with a gross vehicle weight rating over 16,000 lb are exempt too. Your state's title form is where it goes.
I did my own oil changes. Do those records count?
Yes, if they're written down with the date and mileage and backed by the parts receipts. See how to keep a maintenance log for what to record when you do the work yourself.
Should I give the buyer the original receipts?
Give copies and keep the originals until the sale is final. Before you copy them, cover anything personal: your address, phone number and the last digits of a card number.
