What Trajekt does for car, caravan & motorhome dealers

Trajekt is a UK product-feed platform, and a big part of what it does is built specifically for vehicle retailers — car dealers, and the caravan, motorhome and campervan trade. If you sell vehicles and advertise them online, here's what the automotive side of Trajekt actually does, in plain English.

Reads your dealer system directly

Trajekt connects straight to your dealer management system's stock export — such as a Navigator vehicle stock list — and works from that, rather than scraping your website. Your live stock becomes the source of truth for every ad channel, with no website or middleman in the loop. (We wrote a whole piece on why the direct link beats the website chain.)

Builds Google and Meta vehicle ads from one source

The same connection produces a Google Vehicle Ads XML and a Meta Automotive Inventory Ads feed — two very different formats — without you re-keying a single vehicle. Add a channel and it draws from the same stock; it doesn't mean another spreadsheet.

Removes sold stock automatically

Your dealer system already records a vehicle's status. Trajekt reads it: vehicles marked sold are set to out of stock and stop being advertised, while part-exchange or reserved stock that isn't ready yet is handled separately. You're not paying for clicks on vehicles you can't hand over — and no one has to remember to pull them down.

Lets you bid by margin

A DMS export carries both the retail price and your cost — data your website never exposes. Trajekt keeps that alongside each vehicle (without ever publishing the cost to Google or Meta) so you can label and bid by margin: push harder on the stock that actually makes you money, instead of spreading budget evenly across the forecourt.

Handles the UK specifics

Mileage in miles, prices in GBP, and VIN treated as optional — in the UK a VIN is personal data, so Trajekt uses your internal stock number as the identifier instead. Categories like motorhome, tourer and campervan are mapped to the right vehicle type. These are the details that quietly get UK vehicle feeds disapproved, handled for you. There's a fuller rundown in the Vehicle Ads guide.

Keeps the identity that retargeting depends on

Meta's dynamic vehicle ads only re-show a shopper the exact vehicle they viewed when the ID in your feed matches the one your site's Pixel reports. Trajekt can align those so retargeting actually fires — the subject of this post on matching the ID to your URL.

Shows you what changed over time

Because Trajekt records every feed run, you can see your stock health as a trend, not just a snapshot: how many vehicles were live, which went out of stock and for how long, and how prices moved. For a seasonal business — caravans and motorhomes especially — that's the difference between guessing and knowing when to buy and when to push.

The short version

One connection to your dealer system, feeding every ad channel; sold stock that removes itself; margin data you can bid on; and the UK-specific handling that keeps vehicle feeds approved. That's what the automotive side of Trajekt is for — less feed admin, fresher ads, and budget aimed at the stock that sells.
