F1 Miami
Guaranteed Fit Stop
The Guaranteed Fit Stop was consistently packed, drawing long lines throughout the event and quickly becoming a destination within the F1 Miami promenade.
Fans spent meaningful time inside the experience, building vehicles, trying on looks, capturing photos, and sharing their creations. The combination of high-fidelity car customization and fashion-forward expression created a natural bridge between inspiration and confidence, reinforcing eBay’s position as a trusted destination for both parts and style.
Reception
Next Project:
Challenge
eBay Motors was activating its partnership with the McLaren F1 team at the Miami Grand Prix. The brand needed a high-impact experience that could cut through a crowded F1 environment and clearly demonstrate the value of its Guaranteed Fit program to a highly knowledgeable audience of racing fans and car enthusiasts.
Insight
Car enthusiasts put real thought into how they customize their vehicles, using them as an extension of personal identity. Choices around parts, fit, and finish directly affect confidence in the final build. Visual credibility and correctness matter just as much as performance, especially to an audience that knows what they are looking at.
We built the Guaranteed Fit Stop Garage, a real-time vehicle customization experience that let fans design a dream car with total confidence. Powered by Unreal Engine 5, guests explored and customized curated mod bundles and experienced eBay’s Guaranteed Fit promise through hands-on creation.
Our Solution
Set on the promenade of the F1 Miami Grand Prix, the Guaranteed Fit Stop served as eBay Motors’ primary experiential presence during race weekend. Against the backdrop of eBay’s partnership with McLaren Racing and a strong on-track performance, the activation was designed to attract fans moving between races, brand activations, and the surrounding festival environment.
At the center of the space was the Guaranteed Fit Simulator, a digital experience that allowed fans to build and customize a virtual vehicle while maintaining confidence that every part selected was compatible. Framed as a fashion-inspired pit stop, the activation paired exclusive McLaren x eBay apparel try-ons with hands-on car customization, connecting personal style with automotive identity. Together, the experience reinforced Guaranteed Fit as a practical promise that removes uncertainty from buying parts online, while showcasing the depth and flexibility of eBay’s marketplace.
Background
This project played directly to INPHANTRY’s strengths. We approached it as car enthusiasts first, designers and developers second.
Our team hand-sketched vehicles, curated mod packages, and designed configurations we knew would resonate with the crowd. Every proportion, wheel choice, stance, and accessory was informed by real car culture.
We modeled and developed all vehicles and mods in Unreal Engine 5 to achieve real-time lighting, material fidelity, and responsiveness typically reserved for pre-rendered content. To ensure performance in a high-traffic, bandwidth-limited environment, we implemented an offline-first architecture paired with a QR-based takeaway system, allowing guests to access their builds seamlessly after leaving the booth.
The result was a responsive, polished experience that felt both technically advanced and culturally grounded.
