How to list cars for sale online as a dealer
One VIN, one grid placement, one link built for Facebook Marketplace. Here's the actual workflow, done the way you'd do it for a real car on your lot today — not the marketing version.

What listing a car online actually is
Listing a car for sale online as a dealer is the process of turning one vehicle in your lot into a public listing that a buyer can find, share or message about — photos, price and specs included. GridDealer speeds that process up: type the vehicle's 17-character VIN, place it in your grid, and share its own page in minutes.
Plenty of dealers already do a version of this by hand: a photo taken on a phone, a price typed from memory, a post dropped into Facebook Marketplace or a local buy-sell-trade group. That works, sort of, right up until the post scrolls out of the feed and the car is effectively invisible again. A real listing workflow fixes the parts that break down at volume — retyping specs, losing track of what's still active, and having no permanent place to send a buyer back to.
A shareable page isn't the same as auto-posting
It's worth being precise here, because the two get talked about as if they're interchangeable and they aren't.
Software that posts for you
SPARQsites, a $60/mo flat-fee competitor, auto-posts listings to Facebook on your behalf. That's a real convenience, and it comes bundled with a CRM whether you want one or not.
A page built for you to post
Every vehicle gets its own page with your contact info baked in, ready to paste into Facebook Marketplace or Instagram yourself. You do the posting; the page does everything else.
Neither approach is wrong. If hands-off posting matters more to you than price, that's a real trade worth naming, not glossing over.
The four things a listing actually takes
In the order you'd realistically do them.
-
Add the vehicle by VIN
Type the 17-character VIN into a new listing. On blur, VIN decode calls NHTSA's free vPIC API and fills in year, make, model and trim.
-
Add real photos and an honest price
Neither comes from the VIN. Photos and price are the two fields that actually sell the car, so they're worth the extra minute the VIN can't save you.
-
Place it in your merchandising grid
Decide where the new listing sits, and whether it deserves a bigger tile. See how to merchandise your car lot's grid for the full breakdown.
-
Share its own page
Copy the vehicle's link and paste it into Facebook Marketplace, Instagram, or text it to a buyer who asked. Nothing posts on its own — that part is still yours.
Marketplace-only vs. an actual listing
Here's what changes once a car has a real listing behind it, not just a post.
Scroll the table sideways on a phone
| What matters | Before: Marketplace post only | After: A GridDealer listing |
|---|---|---|
| Where it lives | Buried in a feed after a day or two | A permanent page plus a grid slot |
| Specs entry | Typed from memory or the title | Year, make, model, trim from the VIN |
| Contact info | Whatever you typed into that one post | Baked into every vehicle's page |
| Editing after posting | Edit or repost separately, everywhere | Edit once; the shared link updates |
| Monthly cost | $0 | $20/mo, up to 15 listings |
"$0" for marketplace-only isn't a trick — posting to Facebook Marketplace itself is free. What it doesn't give you is a persistent storefront, which is the actual thing you're paying $20/mo for on Starter.
What it costs per car
Starter is $20/mo for up to 15 active listings. Run the arithmetic against your own lot: at 15 active cars, that's $20 ÷ 15 ≈ $1.33 per car for the month it's live (est.). Carry fewer cars — say, 8 — and it's $20 ÷ 8 = $2.50 per car (est.). Either way, it scales with how much inventory you're actually carrying, not a flat number picked for a much bigger lot.
There's no setup fee, and you can cancel any time. If your lot outgrows Starter, Growing Lot is $50/mo for up to 50 listings, Established Lot is $100/mo for up to 150, and Unlimited is $300/mo with no cap.
How to decide what you actually need
Answer these before you list your first car.
-
How many cars are typically live at once?
Count what's actually on your lot right now, not your best month. That number decides which plan tier fits.
-
Are you relying on Facebook Marketplace alone today?
If every sale currently starts and ends inside one post, a persistent page changes what happens after that post scrolls away.
-
Do buyers ever ask you to text them details?
A shareable link with your contact info already on it answers that question once instead of every time.
-
Do you want posting to Facebook automated, or is manual fine?
If hands-off auto-posting matters more than price, weigh that honestly against a lower, inventory-based bill.
Where this isn't the right fit: a lot running 300+ cars with an existing DMS feeding a website automatically doesn't need VIN-assisted manual entry — that lot's bottleneck is somewhere else entirely.
Common questions
Does GridDealer post directly to Facebook Marketplace for me?
No. It builds a shareable page with your contact info on it; you copy that link and paste it into Facebook Marketplace, Instagram, or a text message yourself.
How long does VIN decode take?
It runs the moment you tab or click out of the VIN field — there's no separate lookup step or wait.
What if the VIN doesn't decode correctly?
Every field it fills stays editable. Trim is the one most likely to need a manual fix, since trim naming varies by manufacturer and year.
Can I list a car without a VIN?
Every vehicle needs a VIN to sell legally, so in practice you'll have it. If a field won't decode for some reason, you can still fill in year, make and model by hand.
Do I need a DMS to list cars this way?
No. This workflow is built for manual, VIN-assisted entry — it doesn't require a dealer-management system, and it isn't trying to replace one for a lot that already depends on a DMS feed.
How many photos should I add to a listing?
We don't have a verified minimum to give you here — that's your call based on the vehicle. More angles generally help a buyer trust the listing, but there's no fixed requirement in the workflow itself.
List your first car in the next few minutes
Type the VIN, add your photos and price, place it in your grid, and share the link. That's the whole workflow.
