How to Write a Car Ad That Actually Sells the Car
The single biggest predictor of whether a buyer messages your listing is the cover photo. The single biggest predictor of whether they show up after messaging is the description. Most private sellers under-invest in the second one — short, vague descriptions get short, vague responses, and the listing sits.
This guide is the formula for a description that gets messages from real buyers and filters out the tire-kickers.
TL;DR — what every car ad needs
- A 200-character lede with the headline facts (year, miles, key trust word, price)
- A short body covering history, maintenance, reason for selling, logistics
- Concrete numbers, not adjectives ("$2,400 in receipts" not "well maintained")
- Honest about flaws ("rear bumper has scuff" beats "minor cosmetic issue")
- A platform-appropriate length (200 chars on Facebook Marketplace; 600+ words on Cars.com)
The lede — first 200 characters
Mobile buyers see roughly the first 200 characters before "see more." That's your entire pitch on Facebook Marketplace. Anything below the fold gets read by maybe 1 in 4 messengers.
The format that works:
Single owner. All maintenance records. 89,000 miles. New tires Jan 2025. Clean title. Asking $14,500 OBO.
What's in there:
- Trust signal (single owner, all records, garage-kept)
- Concrete number (mileage)
- Recent improvement (new tires)
- Title status (clean, salvage, lien)
- Price + OBO
Six items, 130 characters. Plenty of room for one more concrete fact if your car has a standout feature ("Carmax extended warranty included," "Just-passed CA smog").
What doesn't belong in the lede:
- Adjectives without numbers ("great condition," "runs perfect")
- Reasons-for-selling ("moving to NYC," "second car")
- Sales pressure ("must sell this weekend," "first $X takes it")
- Negotiation rules ("no lowballs," "firm")
The lede is for buyer qualification, not seller positioning.
The body — short on Facebook, long on Cars.com
Different platforms reward different lengths. The body structure stays the same; the depth changes.
Facebook Marketplace / Craigslist (~250 words):
- Ownership history (1–2 sentences)
- Maintenance and recent service (2–3 sentences)
- Why you're selling (1 sentence)
- Logistics line ("local cash or cashier's check; VIN shared on commitment")
Cars.com / AutoTrader (~600–900 words):
- Headline paragraph (3–4 sentences)
- Ownership history (paragraph)
- Maintenance and service (paragraph)
- Recent work (paragraph)
- Features and options (bullet list or paragraph)
- Reason for selling (1 sentence)
- Logistics paragraph
The substance is the same in both; the longer version expands and adds detail.
The eight things buyers actually want to know
Every well-written car ad answers these eight questions in the first read:
- Year, make, model, trim — exact, not approximate
- Mileage — current, with the date
- Condition — concrete (no accidents, no rust, original paint)
- Title status — clean, salvage, rebuilt, lien
- Recent service — what's been done in the last 12 months
- Why you're selling — short and credible
- What's wrong — anything not perfect, named
- Asking price + flexibility — OBO or firm
Listings that answer all eight get more messages and fewer "is this still available" pings.
Concrete numbers beat adjectives
The most consistently effective single rule:
| Vague | Concrete |
|---|---|
| Well maintained | $2,400 in maintenance receipts; oil changed every 5K |
| Runs great | New brakes Aug 2024; new tires Jan 2025; passes inspection |
| Excellent condition | No accidents per Carfax; no rust; original paint |
| Garage kept | Stored indoors; never seen winter |
| Adult driven | Single owner; commute use only |
| Negotiable | Asking $14,500; will consider any reasonable offer |
The vague version sounds like every other listing. The concrete version forces the buyer to engage with specifics, which surfaces serious shoppers and weeds out scrollers.
Honesty about flaws sells faster
Counter-intuitive but consistently true: listings that name the flaws sell faster than listings that hide them. Buyers will find the flaws at the meet-up; the question is whether you've already priced them in or whether the buyer thinks you're hiding something.
How to disclose:
- "Rear bumper has a baseball-sized scuff from a parking lot — not painted out, included in price"
- "AC blows cool but not cold; estimate from local shop is $400 to recharge"
- "Driver's seat leather has stretched; passenger and rears are clean"
What you avoid: "minor cosmetic issues" (vague — buyers assume worse), "needs some TLC" (red flag).
The disclosed-flaw version filters out buyers who expected a perfect car and surfaces buyers who already accept the flaw.
Logistics line at the end
The closer of every listing should set expectations for the meet-up:
- Payment: "local cash or cashier's check at meet-up"
- Viewing: "available to view in [neighborhood]; weekday evenings or weekend mornings"
- VIN: "VIN shared on commitment to viewing"
- Test drive: "test drive welcome with valid driver's license"
- Tow: (for non-running cars) "buyer arranges tow"
The logistics line filters scammers — "I'll send a shipper," "I'll Venmo it now" — at the message stage rather than at the meet-up.

Common mistakes
Writing in dealer voice. ALL CAPS, exclamation points, "MUST SELL," "PRICED TO MOVE." Facebook's algorithm flags this as commercial inventory; readers tune it out.
Padding with stock features. Listing that the car has "automatic transmission" and "air conditioning" wastes the lede. Buyers assume baseline equipment unless you flag otherwise.
Burying the price. Some sellers omit the price hoping to drive messages. It cuts message volume in half. Price upfront.
Over-promising condition. "Mint," "showroom," "like new" set buyer expectations the car can't meet. The first viewing kills the deal.
Ignoring the question fields. Facebook Marketplace, Cars.com, and AutoTrader all let you preload Q&A. Use them — common questions answered up front cut your DMs in half.
Re-using a 2018 listing template. Listing standards have changed since 2018 — buyers now expect more photos, more disclosure, and more specifics. Recycled old templates read as lazy.
How ListMyCar generates the description
The AI description model writes in the format above by default — lede + body, concrete numbers, flaw disclosure, logistics line. You provide the VIN, the photos, and any specific facts (recent maintenance, why you're selling, anything you want emphasized); the model produces:
- A 200-character Facebook Marketplace lede + body
- A plain-text Craigslist version with fact-list formatting
- A long-form Cars.com / AutoTrader version with all eight fields
You can edit any of it. Most sellers tweak one or two sentences.
Frequently asked questions
How long should a car ad be?
Depends on platform. Facebook Marketplace: 200-character lede + 250-word body. Craigslist: similar, plain-text format. Cars.com / AutoTrader: 600–900 words structured.
Should I include the VIN in my car ad?
You can. Many sellers prefer to share it after a buyer commits to viewing, in a direct message. Sharing the VIN itself is safe; what you don't share is photos of the title document.
What's the most important sentence in a car ad?
The first one. Mobile buyers see only the first 200 characters before "see more." That's the entire pitch on Facebook. Lead with the trust signals and the price.
Should I list the price as OBO or firm?
OBO roughly doubles inbound message volume. Firm cuts message volume but filters for committed buyers. Most sellers should use OBO.
How honest should I be about flaws?
Very. Buyers find the flaws at the meet-up regardless. Pre-disclosing filters out buyers who expected perfection and surfaces buyers who accept the flaw. Disclosed listings sell faster than hidden-flaw listings.
Should I include the reason I'm selling?
A short, credible one. "Moving out of state," "downsizing to one car," "upgrading to a truck." Long, emotional explanations read as desperate or as hiding something.
Can I use the same description on every platform?
Not effectively. Each platform rewards a different format and length. ListMyCar generates platform-specific versions from one upload.
Is a long description always better?
No. Facebook Marketplace buyers skim; long descriptions get cut off in the mobile view. Cars.com and AutoTrader buyers read the full text. Match length to platform.
Should I use bullet points or paragraphs?
Both, depending on the section. Lede and ownership history work better as paragraphs (they read as a person describing the car). Features and options work better as bullets (they read as a checklist a buyer can scan).
What if my car has nothing remarkable to say about it?
Then it's a daily-driver sedan or commuter, and that's a category. Use the daily-driver template — single owner, regular maintenance, no surprises, fair price. Plain-spoken honesty outperforms manufactured drama.
