The difference between a car that sells in three days and one that sits for three months often comes down to one thing: the advert. A well-written listing with clear photos and honest detail attracts genuine buyers. A vague, poorly photographed ad attracts silence — or time-wasters.
This guide breaks down the eight things that make a used car advert work, with real examples of good and bad listings so you can see exactly what to do.
1. Nail the Headline
Your headline is the first thing buyers see in search results. It needs to include the essential details and one selling point that makes them click.
The formula: Year + Make + Model + Trim/Engine + Key Selling Point
The good headline tells the buyer the year, model, spec, mileage, and service history before they even open the ad. The bad headline tells them nothing useful and screams desperation.
2. Include the Essential Details
Buyers scanning ads want specific information fast. Missing any of these creates doubt — and doubt means they move on to the next listing.
- Mileage — Current odometer reading
- MOT expiry date — "MOT until March 2027" is better than "long MOT"
- Service history — Full, partial, or none. Mention if it's main dealer stamped
- Number of previous owners — Check the V5C
- Fuel type and engine size — Petrol, diesel, hybrid, or electric
- Gearbox — Manual or automatic
- Spec highlights — Sat nav, leather, parking sensors, heated seats, Apple CarPlay
- Any recent work — New tyres, recent service, cambelt replacement
- Known issues — Be upfront (more on this below)
3. What NOT to Include
Some things actively harm your listing. Cut these out:
- Personal stories — "Selling because I'm emigrating to Australia" is irrelevant. Buyers care about the car, not your life
- "No time wasters" — This makes you sound hostile and discourages genuine enquiries. Serious buyers don't identify as time wasters
- Vague superlatives — "Drives lovely," "great runner," "never let me down" mean nothing without specifics
- BLOCK CAPITALS — Reads like shouting. Use normal sentence case
- Irrelevant history — The buyer doesn't need to know you bought it from your nan. They need to know the mileage, history, and condition
- Excuses — "Haven't had time to clean it" makes the buyer wonder what else you haven't had time for
4. Be Honest About Faults
This is counterintuitive, but honesty sells cars faster. Hiding faults wastes everyone's time — the buyer travels to see the car, discovers the issue, and walks away. Or worse, they buy it, find the problem later, and you get an angry phone call.
Instead, photograph and describe every known issue. This:
- Builds trust immediately
- Filters out buyers who can't live with the issue
- Attracts buyers who've already factored the fault into their offer
- Protects you legally — undisclosed faults can lead to disputes
For example: "Small dent on rear passenger door (see photo 7). Paint scratch on front bumper from a car park incident, approximately 4 inches long (see photo 8). Both are cosmetic only."
5. Always Include the Price
Ads without a price get dramatically fewer enquiries. Buyers assume either you're testing the market (not serious about selling) or you'll waste their time with an unrealistic figure.
- State a clear price: "£12,495"
- Add "ONO" (or nearest offer) if you're open to negotiation
- If you've priced based on valuation tools, mention it: "Priced in line with AutoTrader and CAP HPI valuations"
- Avoid "offers over £X" — it sounds like an auction and confuses buyers

6. Choose the Right Platform
Where you list matters as much as what you write. Each platform has a different audience and cost structure.
| Platform | Cost | Best For | Watch Out For |
|---|---|---|---|
| AutoTrader | £25–£50+ per listing | Widest audience, serious buyers | Higher cost, competitive market |
| Facebook Marketplace | Free | Quick local sales, casual buyers | More time-wasters, scam messages |
| Gumtree | Free (basic) | Budget and older cars | Lower quality enquiries |
| eBay Motors | Free to list, fees on sale | Auction format, nationwide reach | Must honour winning bid |
| SortedCars | Free | Verified listings, vehicle checks | UK-only marketplace |
For maximum exposure, list on two or three platforms simultaneously. Just remember to remove the ads promptly once the car is sold — stale listings annoy buyers and waste your time fielding enquiries.
7. Respond to Enquiries Quickly
Speed matters. A buyer browsing on a Saturday morning will message three or four sellers about similar cars. The first seller who replies with a helpful, friendly response usually gets the viewing.
- Reply within an hour if possible, especially on evenings and weekends when buyers are most active
- Answer their questions directly — don't just say "it's all in the ad"
- Offer a specific time for a viewing rather than "whenever suits"
- Have the V5C, MOT certificate, and service book ready to show
8. Refresh or Relist If No Interest After 2 Weeks
If your car has been listed for two weeks with little or no interest, something needs to change. Don't just wait and hope — take action:
- Check your price — Is it above what similar cars are listed at? Drop by 5–10%
- Improve your photos — Retake them on a sunny day, in a clean location, with the car washed
- Rewrite the description — Add more detail, fix any typos, and follow the formula above
- Relist as a new ad — On most platforms, fresh listings get more visibility than old ones. Delete the old ad and create a new one
- Try a different platform — If AutoTrader isn't working, try Facebook Marketplace or SortedCars
- Poor photos — Dark, blurry, or messy background photos kill listings. Wash the car and shoot in daylight
- No price — Dramatically reduces enquiries. Always state a figure
- Too vague — "Good condition" and "drives well" tell the buyer nothing. Give specifics
- "No time wasters" — Scares off genuine buyers. Remove it
- Hiding faults — Wastes viewings and damages trust. Photograph and describe every known issue
- Slow responses — Buyers message multiple sellers. The fastest reply wins
- Leaving stale ads up — If the car is sold, delete the listing immediately
Final Thoughts
Writing a good used car ad isn't difficult — it just requires being specific, honest, and professional. Include all the key details upfront, take clear photos, price it fairly, and respond quickly. Do these things and your car will sell faster and for a better price than 90% of the competition.
The best car adverts read like a product specification, not a personal diary. Give the buyer the facts, let the car speak for itself, and make it easy for them to say yes.
When selling a car privately in the UK, you have a legal obligation to describe it accurately. Misrepresenting a vehicle's condition can constitute fraud under the Fraud Act 2006.
