How to Sell More Used Cars at a Dealership: 2026 Weekly Plan

How to sell more used cars at a dealership: step by step

Run these 6 steps in order this week, then repeat steps 1, 5 and 6 every Monday. Your own team controls every one of them.

1. Price each car against its segment's days' supply

Days' supply is the number of days your current inventory would last at the current retail sales pace. Cox Automotive measured the U.S. used market at 2.21 million units and 49 days' supply in September 2026, up from 44 days in August as inventory rose 3.9% and the sales pace fell 6.3%.

Cars priced under $15,000 had only a 34 days' supply, 15 days below the average. Discount those less and sharpen your higher-dollar units first. Each week, compare every car with the same year, model, trim and miles in your local market, and reprice the outliers.

2. Shoot a complete photo set and a video for every car

Photograph each car at intake from the same spot: every exterior angle, the full interior, the odometer, the tires and any damage. Then turn that set into a short vertical video so the car can run as a Reel, a TikTok and a YouTube Short.

CarGurus' 2025 Consumer Insights found 54% of shoppers use phones more than desktops and another 31% use both equally, so vertical video fits the screen they shop on. The same study found 86% still choose to see the vehicle in person before buying. A listing's job is to get that visit.

3. Answer every lead within 15 minutes by text, phone and email

Pied Piper defines a perfect response as an answer to the customer's question by email, text and phone within 15 minutes. 51% of dealers delivered one in its 2026 study, double the rate of 5 years earlier.

The industry scored 71 out of 100, up from 65 in 2025, with dealers texting an answer 54% of the time and phoning 75% of the time. If an AI tool replies first, name the person who takes over complex questions. The study warns about a "digital handoff," where staff assume the automation is handling them.

4. Post every car where used-car buyers look

Cox's Car Buyer Journey Study, released January 13, 2026, found 77% of used-vehicle buyers used third-party sites, 60% used dealer websites, 41% of all buyers used search engines and 26% used social media. Keep every unit live on cars.com, CarGurus and your website, then post the same car on Facebook Marketplace, Instagram, Facebook, TikTok and YouTube.

Buyers visited an average of 4.6 sites, so each car should appear on more than one. Meta sets the rules for dealer listings on Marketplace, so read our Facebook Marketplace Car Dealer Rules 2026: What Changed before you post.

5. Follow up with every shopper who has not bought

CarGurus found that 61% of buyers visited 2 or more dealerships in 2025, up from 54% in 2024, and 53% considered 3 or more brands at the start. Assume every lead and walk-in who left without buying is still shopping. Within the week, send them a fresh video, a similar unit or a price change.

Franchise stores can also offer the other side of the lot, since 66% of shoppers considered both new and used vehicles.

6. Run your aging review at 30, 45 and 60 days

Every Monday, pull every unit that crossed 30, 45 or 60 days and take the action in the table below. These checkpoints are our own working thresholds, and no cited study or NADA figure sets them, so adjust them to your turn.

Move earliest on higher-priced units. In September 2026 the overall market carried 49 days' supply against 34 for cars under $15,000.

Days in stock	What to check	Action	Owner
30	Views and leads on cars.com, CarGurus and Marketplace	Reprice to local market, reshoot weak photos, post a new video	Used-car manager
45	Leads but no appointments	Second price move, repost on Instagram, Facebook, TikTok and YouTube, send to past leads on similar cars	Manager and sales
60	No active deal	Final retail price or wholesale decision	Owner or GM

How long does it take and what does it cost?

You can start every step this week. After that the plan runs as a weekly routine, with a first results check at 30 days.

Most of the cost is staff time you already pay for. Add the price of any new tool, such as A21 Social at $49 to $199 per month plus applicable sales tax (prices checked October 21, 2026).

Task	Who	How often	Cash cost
Pricing review	Used-car manager	Weekly	Your existing market-pricing tool
Photo set	Porter or photographer	Every car at intake	Staff time
Video and social posting	A21 Social	Every listing, automatic	$49, $129 or $199 per month plus tax
Marketplace listing	Sales or marketing staff	Every car	Staff time
Lead response	BDC or salesperson	Every lead within 15 minutes	Staff time
Aging review	Manager, owner or GM	Weekly	Price moves or wholesale loss

Give the plan one full aging cycle before you change the routine. Check at 30 days, then again at 60.

Who should do this?

The owner or used-car manager should own pricing and the aging review, and sales or the BDC should own lead response and follow-up. The photo, video and posting work can go to a porter, a marketing hire or software. That split keeps the manager's hours on pricing decisions.

On a small independent lot, one person may hold every role. Automate the posting first, since it repeats on every car.

Where A21 Social fits in the posting work

A21 Social publishes this blog, so read this section as our recommendation and weigh it accordingly. A21 Social uses AI to turn each car listing into a short vertical video built from your listing photos and details. It then posts the video automatically to Instagram, Facebook, TikTok and YouTube. Nobody on your team films or edits anything, and you don't need an agency.

Your porter keeps shooting the photo set from step 2, and A21 Social makes the video for every listing. Marketplace listings and lead replies stay with your team. To compare options, see our roundup of AI Video Car Dealership Tools: 6 Best Picks for 2026.

Once you pick a plan, check the first videos against your listings so every price shown matches your advertised price.

Common mistakes

The mistakes that undo this plan are advertised prices that break FTC rules, one pricing approach for every segment, and leads nobody owns. The list below also covers sold cars left online, uneven video and late aging moves.

• Advertising a price without required fees. On March 13, 2026 the FTC warned 97 dealership groups about excluding required fees, discounts not available to all consumers and prices conditioned on dealer financing.
• Leaving sold cars online. The same letters flagged advertising unavailable vehicles, so pull sold units from Marketplace, social posts and listing sites the day they sell.
• Pricing every car to the national average. The 49-day market figure sits next to 34 days for cars under $15,000, so price by segment.
• Letting an AI reply stand in for a person. Pied Piper's 2026 study flags the digital handoff risk when staff assume automation is handling complex questions.
• Giving video only to your best units. The cheapest trade-in needs the same photo set and video as the front-line car.
• Waiting until 60 days to act. Your first price and photo move belongs at 30.

How to check it worked

Check results at 30 days and again at 60 by tracking days to turn, response time and leads per listing in your DMS, your CRM and each platform's own stats. Compare each number with the 30 days before you started.

• Days to turn and units over 30, 45 and 60 days: your DMS inventory report.
• Share of leads answered within 15 minutes by text, phone and email: your CRM lead log, measured against Pied Piper's 51% perfect-response rate.
• Views and leads per car: your cars.com and CarGurus dealer reporting.
• Messages per listing: your Facebook Marketplace listings.
• Video views, profile visits and messages: Instagram Insights, Facebook Page insights, TikTok analytics and YouTube Studio.
• Your price bands against the market: the next Cox Automotive used inventory report, compared with September's 49 days overall and 34 days under $15,000.

If your team keeps skipping the video step, A21 Social is our top pick for getting it done without filming or editing. Plans start at $49 per month plus applicable sales tax. Check the A21 Social pricing page and try it on this week's inventory.
