Deal Builder is Auto Trader’s end-to-end online buying journey that allows customers to:
• Reserve a vehicle
• Add part exchange valuations
• Explore finance options
• Select collection or delivery preferences
• Submit a structured, high-intent “deal” enquiry
It’s designed to move the marketplace away from low-quality tyre-kicking leads and towards fewer but far higher-intent interactions.
And the numbers are significant:
• Over 6,000 retailers now have Deal Builder live
• Over 38,500 reservations have been made
• Only 2% of those customers reserved more than one car
• Half of that 2% reserved both cars at the same dealer
This means “stock-blocking” behaviour is almost non-existent.

Busting the Biggest Myths About Deal Builder
________________________________________
❌ Myth 1: “There’s a 0.25% charge per deal.”
✔ Truth: There is no per-deal fee whatsoever.
Auto Trader trialled a 0.25% transaction fee years ago with a small test group — but it was long ago removed.
Deal Builder is included within your regular Auto Trader package.
There is no per-reservation fee, no per-deal fee, and no commission.

❌ Myth 2: “You can’t cancel the sale for 21 days.”
✔ Truth: You can cancel the deal immediately, at any time.
Dealers remain fully in control. From Sales Hub you can:
• Cancel a reservation instantly
• Mark as complete
• Re-open or edit the deal
There is no 21-day lock-in, no cooling-off period forced by Auto Trader, and no restriction on cancelling.

❌ Myth 3: “The £99 goes to Auto Trader or the dealer.”
✔ Truth: The £99 never leaves the customer’s account.
It’s a pre-authorisation only, similar to a hotel or car hire hold.
No money is transferred to Auto Trader or to the dealer.
This setup avoids distance selling complications and ensures the customer is protected — while still signalling genuine intent.
If no action is taken:
• The pre-authorisation releases automatically (around 7 days)
• The reservation flag removes automatically (around 30 days)
________________________________________
❌ Myth 4: “The reservation can’t be cancelled.”
✔ Truth: Both the dealer and the customer can cancel at any time.
Reservations can be removed instantly from Sales Hub, and customers can cancel via their Auto Trader account.
Nothing is permanent, nothing is locked, nothing is forced.
________________________________________
❌ Myth 5: “The car disappears from Auto Trader for 30 days.”
✔ Truth: The car stays live.
A reservation simply puts a ‘reservation in progress’ flag on the advert.
• Dealers can remove it instantly
• Customers can cancel it
• It auto-removes if left untouched
The vehicle is never taken off sale unless the dealer chooses to do so.

A Common Concern: “Customers Now Have to Log In Just to Email a Dealer”
This is a big talking point across social media — and it’s true that Auto Trader now requires a buyer to be logged in before they can send a message or submit a deal.
But here’s the context Auto Trader shared in their latest webinar:
✔ 80% of Auto Trader app users are already logged in automatically.
This means for the majority of customers using the app — Auto Trader’s most active user base — nothing changes.
Why the login requirement exists
Auto Trader introduced this for three main reasons:
1. Better quality enquiries
A logged-in customer has verified contact details, dramatically reducing:
• Fake emails
• Tyre-kickers
• Spam and competitor misuse
2. A consistent, joined-up buying journey
The same login supports:
• Favourites
• Alerts
• Finance tools
• Part exchange
• Deal Builder
• Buying Signals data
It unifies the customer experience.
3. Fraud reduction
The login requirement cuts down bad behaviour on the platform.
The balanced truth
Yes — a tiny number of casual desktop users may drop off at the login step.
But the users who do sign in tend to be:
• More serious
• More engaged
• More likely to convert
In short: higher intent, fewer time-wasters.
This isn’t taking enquiries away — it’s cleaning them up.

Why Auto Trader Built It This Way
Deal Builder is designed to create a buying journey that matches modern retail expectations:
• Higher conversion rates
• Verified customers
• Better buyer insights
• Stronger intent signals
• Reduced admin & wasted time
• Clearer stock visibility
• More online-to-forecourt consistency
And importantly:
Dealers still remain in full control of the vehicle, the reservation, the deal status, and the customer relationship.

Final Thoughts
Deal Builder has created plenty of noise, but a lot of the negativity stems from misunderstandings and outdated information.
Here’s the real summary:
• No per-deal fees
• £99 is only a pre-authorisation
• You can cancel instantly
• Cars never get removed
• Customers rarely reserve more than one car
• Login requirements improve lead quality
• Dealers keep full control
Deal Builder isn’t perfect — no new system is — but the idea that it’s anti-dealer or restrictive simply isn’t supported by the facts.
