6 Steps to Create an Online Car Classified Website (Car Marketplace)

A car classified website allows users to post their cars or automobiles for sale or for rent. Show them to other users who could be interested in buying or renting them.

This could also work for any dealer who wants to sell vehicles through their website. We'll be showing you a step-by-step guide on how to create a car website using Yclas as a platform.

We'll be going through the first steps - standard for creating any classified website regardless of its purpose. 

Get a Domain Name for Your Car Classified Online Marketplace

When you think of a good name for your website, book it as soon as possible. You never know when someone else thinks of the same name or the same idea.

You have many domain registrars. We prefer using Namecheap because it's cheaper than others, it's user-friendly, and we've already had good experiences registering our domain there.

Register a Marketplace Website with Yclas

Go to the Yclas homepage and register your free domain there. The name you choose here doesn't matter since we will be using the domain name you picked in step one later.

You can do this step by typing in your e-mail and any name on the domain. Remember that steps 1 and 2 can be done in any order and you don't need to do one after the other. 

To be able to link your custom domain name, you need to get either a start-up plan or a professional plan with Yclas.

Once you're done with the upgrade link your custom domain to your Yclas account. Note that this could take from 24 to 48 hours to take effect. 

Once you're at this stage, you can go to your domain, and you will find the basic starting view of a Yclas website.

Pick your Preferred Car Marketplace Template

Yclas offers many templates you can choose from. Keepin mind that you can also change the colors, fonts, the look and feel depending on which template you're using.

My favorite template for car classifieds is CZSale.  It shows the car in a big photo in the middle and would get users' attention. The picture in the slider might stretch some cars.

I would recommend using the CZSale if you're making the site to be used by a dealer. This way the dealer can control the quality of the images uploaded. 

My second choice would be the Kamaleon theme due to its customization potential. Since you already have a paid plan with Yclas so you have access to all themes.

Setup Categories and Locations for Your Online Marketplace

Right now, you can go to your website administration panel and add any locations depending on the area your website is focusing on.

So, for example, if you're focusing on Spain as a country, it would be best to add the regions within Spain as locations and the cities in those regions as sub-locations. 

Categories define the way you want listings on your website to be organized. You could either go with just two main categories, for instance, "for sale" and "for rent" or you can be more creative. 

Adding Custom Fields in Your Online Marketplace

Normally this takes a lot of time and effort from you if you would be using any platform to create your own car website. But with Yclas you get a pre-defined set of custom fields that you can add in less than two minutes. 

You can do that by following the steps: 

1. Login to your admin panel
2. Go to settings > custom fields
3. From custom fields templates pick "cars"
4. Click on create

You notice that many custom fields appeared and were created instantly. Those fields are not set to any category, so any user would see them when posting an ad. 

 

The pre-defined set of fields is prepared for car themes. They are based on a standard car classifieds website.

For instance, if a car is being sold by a dealer or a normal user, make, model, and so on are now already on your site as selections.

Those fields will show up as soon as you add them, and the process is that simple if you prefer adding those custom fields into your "motors" category, then you need to put that category in its field before you create the fields as shown in the screenshot below.

Add Icons, Logos and Images

Any user coming to your website now won't recognize that it is car classifieds website until you show them that it is. You can do that by adding some images related to cars or automobiles as banners on your sidebar or homepage. It's all up to you and how you want your website to look when your users come and visit. 

After you're done with all steps, your website is now ready for the big launch, and you're all set; depending on the idea you have in mind, you might want to set up how you receive payments or you could leave it till later. To know more, you can read the guide we prepared on how to set up payments for your website. 

Before You Launch: The Car Marketplace in 2026, in Numbers

The big car portals publish their numbers every quarter, and they make a good benchmark for anyone starting a car classifieds site. Here is the US market as of 2026:

What this means for a new car site:

• The money comes from dealers. The leaders earn from dealer subscriptions, and Cars.com averages $2,500 a month per dealer. A local or niche site can't charge that, but even a small monthly package for local dealers makes the site sustainable. Plan dealer packages (more listings, featured placement) from the start, and keep listing free for private sellers so you build up inventory.
• Lead quality matters more than raw traffic. Cars.com says its 14% drop in unique visitors reflects a deliberate shift towards delivering value to dealers, and its lead volume still grew. A niche site for classic cars, EVs, 4x4s, commercial vans or one region can deliver serious buyers even with modest traffic.
• Cheaper cars are scarce. In Cox Automotive's January 2026 report, vehicles under $15,000 had only 38 days' supply against 49 for the market overall. A site focused on affordable private-party cars serves the buyers the portals struggle to supply.

Dealer rules still apply. In the US, dealers who sell more than five used vehicles in 12 months must display the FTC's Buyers Guide on each vehicle, saying whether it is sold "as is" or with a warranty (FTC). Adding a "warranty / as is" custom field helps dealers stay consistent. The newer FTC CARS Rule on dealer advertising will not take effect: the Fifth Circuit vacated it 2-1 on 27 January 2025 because the FTC skipped a required procedural step, without ruling on the rule's substance (Holland & Knight, February 2025).

On Yclas, dealer packages map onto monthly membership plans and featured listings. You can try them with a 15-day free trial, and the Starter plan costs $19/month for the first 6 months, then $69/month (see pricing).

This page also replaces our older posts on building a car dealer marketplace and on starting a classifieds site for cars, trucks and RVs.

What private sellers pay on the big sites

Before you set your own prices, look at what sellers already pay, because that is what you compete with. We checked these on 8 October 2026:

For a niche site, such as RVs, classic trucks or one region, basic private listings must be free or nearly free to attract inventory. Earn your money from dealers, featured placements and add-ons, and win buyers with better data and trust than a general site offers.

More on the FTC Used Car Rule

• Where and how much. According to the FTC's Dealer's Guide to the Used Car Rule (edited January 2025), the rule applies everywhere in the US except Maine and Wisconsin. The Buyers Guide also says what share of repair costs the dealer will pay, and the FTC says violations can cost up to $53,088 per violation.
• Which vehicles. The Buyers Guide covers every used car a dealer offers for sale, including vans and trucks. Motorcycles and most recreational vehicles are not covered, so for RV dealers ask for the warranty terms in the ad itself. Ask dealer accounts to upload the Buyers Guide with the photos.
• Online sales too. The FTC's consumer advice Buying a Used Car From a Dealer (April 2024) says buyers are also entitled to a Buyers Guide when they buy a used car online. It tells shoppers to get out-the-door prices in writing before they visit, and to make sure spoken promises are written on the Buyers Guide. Show the full price clearly, and give buyers a messaging channel so the seller's answers are kept in writing.

Point buyers to history, title and recall checks

The US government's National Motor Vehicle Title Information System (NMVTIS) sells reports that show a vehicle's current title and brand history (such as junk, salvage or flood), its latest odometer readings, insurance total-loss determinations and transfers to salvage yards. Asking sellers for the same facts up front and linking buyers to an NMVTIS report reduces "title washing", where a damaged car is re-registered in another state to lose its brand. With the VIN, buyers can also run a free open-recall check on NHTSA's recall lookup.

The FTC adds that a history report "is not a substitute for an independent vehicle inspection", because it usually won't show mechanical problems. A short "Before you buy" page that links to both, and a safety tip next to the contact form, is one of the cheapest ways to cut scams and disputes.

Fields to add next to the Cars template

The Cars custom-field template already creates fields for For sale by (Owner / Dealer), ad type, year, make, model, kilometers, body type, transmission, drivetrain, color and fuel type. Add a few of your own so every ad answers what buyers ask most:

• VIN (text): lets buyers run their own history, title and recall checks.
• Warranty (select: As is / Dealer warranty / Manufacturer warranty): matches the Buyers Guide wording.
• Title status (select: Clean / Salvage / Rebuilt): the facts NMVTIS reports on.
• Inspection available (yes/no): signals sellers who accept an independent mechanic.

Keep year, make and model as dropdowns, because free-text spelling breaks your search filters. NHTSA's free vPIC vehicle database is a reliable reference for make and model names. It returned 12,383 make records when we queried it on 8 October 2026. Mark the fields required and searchable, and buyers can filter out salvage titles or as-is sales in one click.
