Understanding the Problem

Design approach to identify key objectives and improvements:

Problem Statement

Current CPO vehicle marketplaces focus on inventory listings rather than helping buyers make informed decisions, creating a missed opportunity to deliver greater customer value and differentiate the buying experience. Buyers need a trustworthy, AI-powered platform that transforms complex market data into clear, personalized insights, enabling them to evaluate vehicle value, determine the best time to buy, and negotiate with confidence.

Research Approach

Conducted qualitative interviews with Porsche CPO buyers to understand their buying behaviors, pain points, and trust in AI. Research insights directly informed the personas, product strategy, and AI-powered features designed to improve pricing transparency, purchase confidence, and decision-making.

Key Findings

Users wanted transparent, explainable AI that clearly showed the reasoning behind recommendations and helped them make informed decisions—not just browse vehicle listings. They also valued predictive insights and personalized guidance to confidently evaluate vehicle value, determine the best time to buy, and negotiate with data-backed evidence.

Designing & Calibrating AI

AI Fair Market Pricing: Predicts fair vehicle value using market data and comparable vehicles.

Buy Now vs. Wait Predictions: Forecasts price drops and market trends to recommend the optimal purchase timing.

Smart Vehicle Comparison: Aggregates and normalizes listings across dealerships for easy side-by-side comparison.

Negotiation Intelligence: Provides data-driven negotiation strategies based on dealer behavior and historical pricing.

Explainable AI: Makes recommendations transparent by showing the data and reasoning behind each insight.

Personalized Recommendations: Adapts insights, alerts, and guidance based on each buyer's preferences and goals.

Designed to Empower

Through predictive analytics, explainable AI, and personalized recommendations, users can confidently evaluate vehicle value, compare options, determine the best time to buy, and negotiate with data-backed evidence rather than guesswork.

Designed for Explainability & Trust

A major finding from the user interviews is that buyers do not simply need more information: they need to trust it enough to act on it. Participants consistently expressed skepticism toward dealership pricing and AI-generated recommendations, particularly when they could not understand how conclusions were reached. Therefore, the design goal was not to maximize trust blindly, but to appropriately calibrate trust by helping users understand when the AI is likely to be reliable and when they should apply additional judgment.

Designed for Confidence

CPO Wizard provides confidence to buyers by transforming complex market data into clear, actionable insights. By combining predictive analytics, real-time market trends, dealer behavior, comparable vehicle analysis, and explainable AI, the platform helps users evaluate vehicle value, identify the best time to buy, compare options, and negotiate with confidence.

Designed to Transform CPO Vehicle Shopping

Platform transforms CPO vehicle shopping from a listing experience into an AI-powered decision support platform that helps buyers evaluate value, determine the best time to buy, compare vehicles, negotiate confidently, understand dealer behavior and trust AI recommendations through transparency and personalization.

Our Results

User testing validated that buyers preferred an AI-powered decision support experience over a traditional vehicle listing site. Features such as Fair Market Pricing, Buy Now vs. Wait predictions, Negotiation Intelligence, and Explainable AI increased users' confidence by helping them understand vehicle value, market trends, and the reasoning behind AI recommendations.

The research demonstrated that combining Predictive Analytics, Market Intelligence, and Transparent AI can reduce the time and effort required to research, compare, and negotiate CPO vehicles. It also reinforced the importance of personalized decision support, showing that buyers with different goals benefit from tailored insights and varying levels of explanation, transforming the experience from a transactional marketplace into a trusted decision-making platform.
