I think somehow in my last UI attempt “The landing page” I managed to implement the Z design pattern without even trying (yay me). The Z pattern is basically a layout that makes use of how people scan screens (in the western cultures) left to right, top to bottom. Important elements are located at the end points and elbows of the Z. A full explanation of the Z pattern can be found on creativebloq.

The logo (very important) is located top left – identifies the site owner. The eye tracks right across the main nav. The end of the main nav is often where the search is located. It then goes down via the main image to the bottom left button to the bottom right. The last button on the bottom right could be a call to action such as ‘Buy now!!’…not sure people actually buy new cars online, having only had second hand myself, so I thought reading some good reviews might be persuasive instead, but you get the idea.
