Used Car Price & Mileage Visualizer

An interactive chart-based search tool for used cars where each dot represents a listing, with mileage, price, and age instantly visible. Makes comparing cars faster and more intuitive than traditional lists.

Used car search is a frustrating experience dominated by list-based UIs that haven't meaningfully changed in a decade, and with used car prices still elevated post-pandemic and buyers doing more research before purchasing, there's genuine demand for better comparison tools. CarGurus is the closest incumbent and already does some scatter-plot style price analysis, which is a real risk — not a startup, a well-funded incumbent with the same insight. Revenue is the core problem here: without proprietary listing data, this tool depends on scraping or API access from platforms that have every incentive to block or charge you, and monetization likely requires either affiliate deals (thin margins, platform-dependent) or a subscription that most casual car buyers won't pay for. The most likely failure mode is getting cut off from data sources before finding a repeatable revenue channel, leaving a technically interesting but commercially stranded product.
