How Redesigning a Used-Car Detail Page Boosted User Decisions and Business Value

Used‑car sales are a core business for the group, and the product and design teams continuously explore upgrades to provide a high‑quality, end‑to‑end service experience across scenarios such as finding, selecting, viewing cars, and connecting with dealers. User interviews, consistency reviews, product collaboration, and competitive analysis revealed several product issues beyond the visual layer on the existing detail page.

The redesign aims to:

Further improve user decision efficiency

Provide dealers with appropriate display entry points to drive commercial value

Enhance business consistency

Optimize information presentation and page quality

Increase vehicle authenticity and service assurance

The article explains the process and thinking behind the redesign across multiple dimensions.

Changing Collaboration Methods

The design workflow now encourages designers to shift from merely receiving requirements to providing design support, fostering tighter, more efficient, high‑quality cross‑department collaboration throughout the product design and development process. This requires greater focus on requirement collection, evaluation, synchronized design, communication, cost assessment, and continuous validation of design, product functionality, cost, and value across project phases.

Design Implementation

Further improve user decision efficiency

The detail page’s core goal is to present suitable vehicle information to convert viewing into phone contact, achieving product objectives. Proper information structure and efficient information retrieval affect perceived vehicle authenticity and assurance, influencing final decisions.

1. Build a more reasonable main framework with modular display

Based on research and competitive analysis, information is prioritized into seven modules: image/video, price, basic info, 3D view, guarantees, seller, and recommendations, aiming to boost reading efficiency through clearer, modular presentation.

2. Consolidate information, reduce redundancy, highlight key data

Previously, basic information was scattered across two modules and not visible on the first screen. The redesign integrates basic vehicle details, removes unnecessary fields, and provides an entry for additional configuration, increasing useful information density on the initial view.

3. Expose inspection reports and service guarantees to create authority

The vehicle inspection report uses a simulated paper format with a seal, clearly showing problematic components identified by the inspector, helping users understand vehicle condition.

Service guarantee and insurance modules integration

Leveraging the platform’s viewing, inspection, and extended warranty services, the guarantee module enhances perceived platform assurance.

Introducing the guarantee module strengthens user confidence after obtaining basic information.

4. Optimize guidance to stimulate user actions

The previous phone‑call prompt was insufficient. The redesign changes the interaction: after a user stays on the page for a certain duration, a pop‑up appears with motion cues, making the call‑to‑action more intuitive than the prior bubble design.

· Optimize dealer display entry to improve content compatibility

Dealer names were often too long for the original layout. The redesign adjusts the structure, moving the “Enter Store” and “Inquire Price” buttons below, ensuring compatibility. Fields like call‑connect rate and sold/available vehicles are de‑emphasized based on research, while rating integration is strengthened.

· Service, operation, and dealer certification display upgrades

From a commercial perspective, the redesign reserves space for operational activities on the first screen and adds a certification module for verified dealers, maximizing visibility during campaigns.

· Enhance business consistency

As a platform‑level product, the design aligns with the platform’s component library, adopting new spacing standards and card components to maintain a consistent visual style across car‑related scenarios.

Reusable Extended Design

Each redesign of the used‑car detail page impacts other categories such as freight and logistics. The new design language is therefore built to be easily reusable across these business lines.

Quantifiable, Manageable Iteration

Design iteration follows the platform’s TOOLKITS guidelines. Using iWiki and iWork, each design is quantified, documented, and shared to facilitate cross‑department communication, requirement management, tracking, and knowledge accumulation.

Finally, the overall redesign effect is showcased.

Summary Review

The project progressed from requirement discussion, interaction design, visual design, delivery, to development integration. Designers deepened business understanding, completed the redesign within one release cycle, and aim to continuously explore further scenarios to drive conversion goals and business evolution. Thanks to the dedicated interaction, product, testing, and development teams.
