Choose Used Car Redesign Wireframe

Wireframe of Revised Choose Used Car Page

1) The flows for the new and used car are now congruent, the user may select and compare new and used cars at the same time. Although the details of the interface will adjust from new to used car selection, the flows are parallel and have an overall similar experience. The interface will update accordingly depending on which is selected.

2) Refining the search becomes an optional step in the process and is clearly part of the process and not something that is overlooked and off to the side as in the initial flow. Sliders make it easier to see the range you are selecting and give the user finer control over lists of ranges selected from drop boxes.

3) The search results do not differ from original flow.

4) What does differ is the ability to see the details of the selected car on the search page, prior to continuing on with a selection. So as the user selects different options, the 'photos', 'specifications', 'dealer notes', and 'reviews' can be seen in context of the selection. In the old flow all of these details required several clicks past the selection, so if the details were not desirable the user had to start at the beginning and go through the flow again.

5) The next step is clearly called out and is consistently found just above the fold. On longer pages, a second button can be inserted at the bottom of the page.

6) Indicates below the fold.

7) The original search page(s) are split between entering your zip code and...

8) the actual make and model search. Note the confusion of the steps, and how each page claims to be the 'choose your used car' step. As does the following page that describes the details of the selection.
