My work:
Wireframing concept and Prototype of Verivox listing page
Wireframing for Verivox cars listing page
UX Process
After reviewing and researching UX on other websites with similar topic, I have presented this layout to client, which was the best ratio of available / visible information in comparison to all available devices. Regarding development "style" I've choosen device agnostic information flow with heavy responsive CSS usage, therefore skipping the need for mobile app.
