Male, 64 years old, has a good understanding of vehicle specifications
Test and observation process:
- Did not immediately notice the quick filter section on the home page—mistook it for a decorative element
- When using the price filter, he got confused about the range: he tried to select “up to” but set it as “from”
- The filter sometimes “glitched” after selection—the settings were reset, which was frustrating.
- When selecting a car, he noticed that several specifications were missing from the card
- I agreed with the idea that it would be more convenient to place the filters in the left column so that the search results would automatically update on the right without having to click a button.
<aside>
Key findings:
The user did not immediately understand how to start the search and spent time figuring out the filters. Errors with the range and the reset of filters prevented the task from being completed.

Female, 53 years old, with a basic understanding of cars
Test and observation process:
- She also didn’t notice the quick filters on the home page and started looking for the main filter section
- When setting the price filter, she also got confused by the range logic: instead of “up to €16,000”, she set “from €16,000”.
- She noted that the filter interface doesn’t look intuitive—there are too many steps before applying the settings.
- After experimenting with the filters, she said that she wouldn’t have known how to use them correctly without an explanation.
- She agreed with the idea of placing the filters on the side (on the left side of the screen), where they would be constantly visible.
<aside>
Key findings:
The user felt uncertain about working with the filters and experienced cognitive load. Errors in the range and the unclear structure confirm the interface’s complexity for beginners.

Male, 20 years old, has a good understanding of car specifications and actively follows the used car market
Test and observation process:
- At first, he didn't understand which page to go to in order to start a search. The navigation between sections wasn't clear.
- When setting up filters, he noticed that it’s impossible to specify an exact numerical value—you can only move the slider, which reduces specificity and is annoying.
- He noted the absence of a search bar by model name, making it impossible to quickly find a specific car.
- Suggested adding information about the transmission to the car description, considering this an important technical specification.
- Confirmed that placing the filters on the left side of the page would make the search more convenient and intuitive.
<aside>
Key Findings:
Navigation needs refinement, and filters need to be more precise. The lack of an input field for numerical values and a search by model name significantly slows down the car selection process.

Female, 25 years old, confidently understands car specifications
Test and observation process:
- Successfully configured the filters according to the specified parameters, but noted that it was impossible to enter specific values manually
- Believes that the current number of categories is sufficient, but that the interface could be structured more logically.
- Confirmed that placing the filters on the left would be more intuitively familiar, especially for users with experience shopping at online stores.
<aside>
Key Findings:
The filter functionality limits users who want to set specific parameters. Overall, the interface does not cause significant difficulties, but requires improvements in accuracy and layout logic.
