A ground-up redesign of Spinny's live car-auction listing page - built for speed, scannability, and split-second bidding
* Before shipment vs after shipment · numbers rounded off
Source stock without chasing the market
Spinny Partners is the app 80,000+ used-car dealers use to source their cars - thousands of inspected cars in live auctions with verified condition reports, so buying stock is fast and low-risk instead of guesswork across the market
Thousands of inspected cars, each with a verified condition report
Every car goes live for a set window - dealers place their bids
The highest bid moves ahead on the car
Settle the final price with the seller, right in the app
Pay after inspection - the car is delivered to the door
of a dealer's stock was going to Cars24 - and it won on two fronts
Two research methods, run in dealers' own shops
Sit beside dealers & watch them bid - how fast? what first? where do they struggle?
Every piece of card info, sorted by importance - thinking aloud
Every dealer checked the engine rating - though half didn't fully trust it
Sorted two ways — what was broken, and what was missing.
Nearly the entire dealer base passes through the product listing page, daily
Where we looked
Ship, test, improve, repeat
10+ dealers rated every change
Same car, half the noise
Banners, ID, make, unread tags & CTAs - gone 10/10 dealers approved; some wanted more cut
Dealers read colour & variant from photos most-loved change
A speaker icon for models dealers listen to (Polo, Vento) loved once understood
“Accidental” not “structural”; Prime & Select defined inline clarity = trust
Other iterations that didn't make it
The same system, scaled to bigger canvases
17% of our high-transacting dealers use foldables - enough reason to design for them too
* Before shipment vs after shipment · numbers rounded off
The 40% drop in missed cars is the one I'm proudest of - proof dealers could finally read a car and act before the clock beat them. This was the "easier page" half Cars24 was beating us on; inventory stays a separate, ongoing bet
We will make this even better
On a timer, every element cut is speed returned
Shops surfaced what surveys never would
“Accidental” vs “structural” = trust or confusion
Loved once understood - not before
Five releases beat one perfect launch
20+ A/B tests over opinions
Rebuilt Spinny's live-auction listing page for speed, clarity & split-second bidding
Where dealers bid on inspected cars to source stock
Watched dealers bid + usability & card-sort sessions
26 issues - clutter, tiny ratings, evasive copy
Removing is a feature · watch, don't ask
