Finance, part-exchange and reservations, threaded into the marketplace — with the forecourt kept as the thing that earns the trust.
Results
A service-led, trust-anchored blended journey — guaranteed part-exchange, plain-language finance, and a £199 fully-refundable reservation, brought into the vehicle page itself. We rejected the “buy blind” model the disruptors raced toward; its later collapse proved the call.
Could Auto Trader bring part-exchange, finance, reservations and options into the search experience — without breaking the trust the marketplace had earned over 40 years?
The problem
Auto Trader already owned the audience and the attention. The gap wasn't demand — it was a missing, trusted way to finish the deal online without asking buyers to "buy blind".
The design tension
Bring the journey online — without taking it off the forecourt.
The market proved people would buy online; it couldn't say how to move them. Three calls set the direction — each one later borne out.
The research was unambiguous: online is a spectrum, not a switch. Most buyers want the anxious admin done from the sofa, then the right to see the car in the flesh.
So we killed the fully-online model before a screen was drawn and kept the forecourt as the trust anchor. The disruptor who designed it out later collapsed.
Read the research →The bottleneck was never demand — it sat between a record audience and a deal they were ready to do. “Build buy buttons” was the wrong brief.
We broke trust into competence, dependability and integrity and designed against those — reframing the job as “moving customers to action.”
See the reframe →Auto Trader already owned the audience and 40 years of trust. It didn’t need a new place to go; it needed to finish a journey millions were already on.
Finance, part-exchange and a £199 refundable reservation brought inline on the vehicle page — start online, finish human.
See the experiments →The blocker was confidence, not capability. Every screen earned its place by removing a moment the buyer could feel unsure — a lowball at the gate, a term nobody explained, a leap taken blind.
Asset-light and trust-anchored was the unglamorous call while a rival burned cash to own the whole transaction. The research drew the line at the forecourt; the bet aged well.
Confident enough to get out of the Connoisseur’s way, reassuring enough to walk the Explorer through — built for 17 to 70+, without averaging either into blandness.




Start online, finish human. Confidence didn't come from removing the dealer — it came from letting people do the anxious admin privately, then arrive already sure.
An online-only player was proving, in public and at speed, that people would complete the whole journey online — and capture the finance and ancillary revenue our classified model never touched. "Wait and see" had a price tag that rose every quarter. The prize: Europe's $700bn used-car market was under 2% online.
The market told us that people would buy online. It couldn't tell us how to make them. So we went and asked them.
Most buyers don't want fully online. They want to do the anxious admin from the sofa, then keep the right to see the car in the flesh. That insight killed the "buy blind" model before we drew a screen.
Experienced, love the research, know what they want. Comfortable completing online — sometimes impulsively.
More nervous, less sure, need reassurance. Treat the dealer as a proxy guarantee and do less of the journey online.
One journey had to carry both — confident enough to get out of the Connoisseur's way, reassuring enough to walk the Explorer through.
"You see it from one side on the internet. When you go in, you see the reality… I need to get it right."
"From experience I completely trust it — as long as you've done your research and know what you want."
The buying process is overwhelmingly visual, and every step is a potential exit back to the forecourt. But the levers that keep people online were universal across every buyer and every sector we looked at:
Synthesised across the qual and the market data, the buyer's own words pointed at one answer: the ideal online experience blends the best of offline with online — to build trust and confidence. Auto Trader didn't need to become a retailer. It needed to extend what it was famous for, carrying 40 years of earned trust the whole way. We broke "trust" into something we could actually design against.
The product works — quality checks, accurate valuations, a quote that holds.
One consistent experience across every platform and channel.
No pressure, no ambush, honesty about the good and the bad.
The friction-heavy steps buyers were begging to start from the sofa — captured as committed deals, not cold leads, wrapped in assurances that engineer confidence.
The inspection, the test drive, the human anchor. The disruptor who designed this out would later prove the point the hard way.
Not online vs forecourt. Not products vs journey. A service-led, trust-anchored blended experience — and everything that followed was built to deliver it.
The "buy blind" model (Cazoo) removed friction by removing the forecourt — and with it, the trust anchor. We rejected asset-light full-online purchase as the wrong bet for this audience. Cazoo's later collapse retroactively validated the call.
Trust had to be made felt at the three moments confidence collapses: valuing the car you're trading in, working out finance, and the leap from sofa to forecourt. We prototyped and tested each — lo-fi first, brand protected, the "Helen" voice carried from the products that already worked.
The fear was never the form. It was being low-balled at the gate — so people never started the deal at all.
A valuation only builds confidence if the buyer believes the number and didn't have to fight for it. So GPX became a calm self-appraisal you do from your own driveway, ending in a guaranteed price, held for seven days.


The result screen does the one thing a lowball quote never does — it shows its working: the condition you reported, live market value, the data behind it. Then it hands control back: take it as cash, put it toward a car, or advertise privately.
A fixed price, full transparency, control. Remove the ambush and you remove the reason people abandon the deal before it begins.
The full GPX self-appraisal, rebuilt in React from the Figma. Answer the questions and watch the guaranteed price recompute live — the thing static screens can't show.

Finance is where confidence goes to die. Four acronyms, a fear of being trapped, and numbers nobody explains.
The industry leads with the jargon and lets the buyer drown. We did the opposite — collapsing four finance types into two plain-language choices: pay less now and decide later, or own it outright at the end. Helen guides the rest.
Plain language, a named human, worked examples. Confidence in finance isn't won with a better calculator — it's won by removing every moment the buyer feels stupid for not knowing a term.
"Online versus forecourt" was the wrong question. Buyers wanted to start the deal from the sofa — and finish it like a human.
The disruptors built destinations and asked people to buy blind. Auto Trader didn't need a destination — it had the audience and the trust. The job was to thread finance, part-exchange, reservations and delivery into the vehicle page itself, while keeping the forecourt as the anchor for the moments that still need a human.
Every flow ran through task-based usability sessions before it was resolved into UI — measuring comprehension and confidence, not just clicks.
Decisions ran through the brand-experience wheel and five fundamentals. "Helen" — the calm, jargon-free voice from Finance & GPX — was protected, never diluted.
Designed for both segments and every ability: confident enough for the Connoisseur, reassuring enough for the Explorer.
