Colorado’s dealer advertising rules, applied to Facebook Marketplace
What a Marketplace listing for a dealership car has to say in Colorado, what it can’t say, and where each rule comes from. A checklist for GMs, sales managers and F&I.
The short answer
- Name the dealership and say it’s a dealer. (C.R.S. 44-20-134)
- Any price needs the year, make, model and stock number, or the full 17-character VIN. (Rule 3)
- The price has to include every cost at delivery except sales tax, finance charges, emissions testing, other government fees and taxes, and delivery the buyer asks for. Dealer handling and doc fees go inside the price. (Rule 13)
- You honor the price for 3 days after the ad last runs unless it gives an end date, so put a good-through date on it. (Rule 3)
- No payments, down payments or rates unless the full credit disclosures go with them. (Regulation Z)
- Leave out “invoice,” “dealer cost,” “wholesale,” “write your own deal” and “we won’t be undersold.” (Rules 9 and 11)
Most Colorado stores now get their cars onto Facebook Marketplace through their salespeople, each posting from their own profile. It’s cheap, it works, and it moves a lot of advertising out of the marketing department and into the hands of people who were never trained on the state’s ad rules. This is the checklist we wish every store had taped next to the sales desk.
Does a salesperson’s listing count as a dealer ad?
Treat it as one. Colorado’s advertising statute, C.R.S. 44-20-134, applies to dealers and to their agents, and a salesperson posting the store’s inventory to sell the store’s cars is acting for the store. The Dealer Board’s advertising rules, Regulation 44-20-121(3)(i), don’t carve out social media or one-off listings either. That’s the cautious reading, and it’s the one we built KeyTurn Logic around. If your attorney reads it differently, go with your attorney.
There’s a second reason. A listing posted from a personal profile looks like a private sale unless it says otherwise, and that impression is exactly what 44-20-134 is written to stop: a dealer ad can’t suggest that a private party is selling, and it has to carry the dealer’s name and the word “dealer” (or a name that makes it obvious).
The checklist
| What the listing needs | Where it comes from | What it looks like on Marketplace |
|---|---|---|
| The dealership’s name and the word “dealer” | C.R.S. 44-20-134 | First line of the description: “Offered by Example Motors, a dealer in Denver, CO.” |
| Year, make, model and stock number (or full VIN) with any price | Rule 3 | The title carries year, make and model; the description adds “Stock #R2210” and the VIN. |
| An all-in price | Rule 13 | The price box shows Internet Price plus the dealer handling fee. The description shows the breakdown. |
| An end date on the price | Rule 3 | “Good through Nov 20, 2026.” |
| Photos of the car you’re selling | Rule 4 | The car’s own photos from your feed, not a stock image of a different year or trim. |
| Say so if it isn’t on the lot | Rule 3 | “In transit” or “on order” near the top, never implied to be in stock. |
| Salvage, rebuilt or flood history disclosed | Rule 7 | “Rebuilt title” stated plainly in the description. |
| Used never presented as new | Rule 6 | Mileage in the details, and no “brand new” language on a used unit. |
The fee problem with feed-built listings
This is the one most stores get wrong. Your inventory feed sends each car’s Internet Price. A posting tool that drops that number straight into Marketplace’s price box advertises a price that leaves out your dealer handling fee.
Rule 13 says an advertised price has to include all costs to the buyer at delivery, with a short list of exceptions: sales tax, finance charges, emissions testing, other government fees and taxes, and transportation the buyer asks for after the sale. A dealer handling or documentation fee isn’t on that list. Writing “plus $699 dealer fee” under the price doesn’t fix it, because the advertised number still leaves the fee out. The fee has to be inside the price.
A listing that gets it right looks like this:
- Internet Price
- $34,995
- Dealer handling fee
- $699
- Total advertised price
- $35,694
The price box says $35,694. The description shows the same breakdown, the good-through date, and the store’s approved line about what isn’t included (sales tax and government fees). Get that wording from your attorney once and use it everywhere.
Three days, unless you say otherwise
Under Rule 3, a car advertised with a price has to be sold at that price for three days after the ad last runs, unless the ad states a time limit that has passed. On Marketplace, a listing keeps running for as long as it’s up. So a listing that’s still live after a price increase is a promise at the old price.
Two habits cover it: put a good-through date on every price, and update or take down every live listing when a price changes. Increases first, since those listings advertise less than the car now costs.
Payments and rates stay out of listings
“Only $489 a month” is a triggering term under federal Truth in Lending rules. Under Regulation Z, 12 CFR 1026.24(d), an ad that states the amount or percentage of a down payment, the number of payments or repayment period, the amount of any payment, or the amount of any finance charge must also state the down payment, the terms of repayment and the annual percentage rate.
A Marketplace description isn’t built to carry that, and the numbers depend on the buyer’s credit anyway. “Financing available” is fine. A payment, a rate, a down payment or a term length is not, unless the full disclosures go with it.
Words to leave out
The Dealer Board names specific wording as misleading. These come up in Marketplace listings more than you’d think:
- “Write your own deal,” “name your own price,” “no reasonable offer refused,” “we will not be undersold.” Rule 9 treats these as creating the false impression that the buyer sets the terms. The same rule bars calling something “free” when the buyer only gets it by buying the car.
- “Dealer cost,” “invoice,” “wholesale.” Rule 11 bars any reference to dealer cost or invoice price, and the word “wholesale” in a retail offer.
- “Everybody financed,” “no credit rejected,” “we finance anyone.” Rule 18 allows these only if they’re true, meaning no applicant is ever turned down.
- “Priced below KBB,” “save $3,000.” On a used car, Rule 10 requires you to be able to document what the savings is measured against.
Where to start this week
Pull up five live listings from five different salespeople. Check each against the table above. If the price box shows the Internet Price, the fee is outside the price on every one of them, and that’s the fix to make first.

How KeyTurn Logic handles it
Every listing KeyTurn Logic hands a salesperson is built from your inventory with the dealer named in the first line, the stock number and VIN, the all-in price with its breakdown, and a good-through date. It’s checked against these rules before anyone sees it, and a listing that fails isn’t handed out. When a price changes, the salesperson who posted that car is told and the new wording is ready to paste.
