Joautok.hu is a fact-checked used car listings platform award winner of the best website in 2017. We conceived and tested all interfaces for mobile and desktop.

The case

Buying a used car is a long and bumpy road riddled with many difficulties for the potential buyer. Many of these difficulties stem from the lack of information for the buyer about the seller or the offered vehicle.

  • Balázs-Tárkány Kovács – UX Designer

The client’s objective was to create a used car advertising portal featuring only verified
and documented vehicles and sellers.
Many of these difficulties stem from the lack of information for the buyer about the seller
or the offered vehicle. This creates a lot of uncertainty when searching as well as additional
work during the selection process, and may generate great disappointment and even
financial loss once the deal has gone through.

Wireframes of joautok.hu

Identifying a clearly defined pain point in the user journey is always a great opportunity to do things better and to create processes, functions and interfaces that help the user solve or avoid a specific problem. The client envisaged a portal where sellers undergo a central qualification procedure and vehicle history is corroborated by uploaded documents and certificates. Besides creating the UX concept for the well-defined USPs, we were also tasked with designing up-to-date solutions that would make the process of buying a car easier and more successful and offer a superior user experience during both the search, selection and buying process.

Opening page

The UX design phase was preceded by thorough business planning that included both demand and supply side research. We then started crafting the UX concept based on the personas, user journeys and feature lists thus created. The next stage of concept development involved drawing the wireframe of the main pages of basic functioning and designing user flows describing functioning.

Product detail page

Clickable prototypes were made from the wireframes and were used to carry out the first user tests. We fine-tuned the wireframes leveraging information from the tests and continued designing the other pages. Before starting the development stage, we build MVP package based on business priorities. After designing and developing the package, the first MVP status version of the portal was published.
