Carpool: Used Car Value Ranker

Ranks Facebook Marketplace and Craigslist cars by cost per remaining mile and saves them to your Carpool lists.

Carpool shows what a used car really costs: its price spread over the miles it has left, plus fuel if you set a gas price. Now it works right on Facebook Marketplace. • A badge on every vehicle listing shows its cost per remaining mile, a value rating from Excellent to Poor, and its rank among the cars you've seen. • Open a listing for the full breakdown: expected lifetime miles for that model, miles remaining, percent of life used, EPA fuel economy, and links to Kelley Blue Book and CarComplaints. • Add any car to your current list, a saved list, or a new list in two clicks. Price, mileage, and the listing link come along. • The side panel ranks every car you've scrolled past in the last 14 days, with search and filters, and keeps your lists at hand. • Spot dealer bait: mark a listing "Do not buy" and other Carpool users who find it see the warning. Their warnings show up for you too. • Sign in to sync your lists and your log of cars across devices, or use it without an account. Carpool shares the vehicle listings it scores with Carpool to build used-car market data; you agree to this before the extension starts. Lifetime estimates cover 2000–present models and come from Carpool's catalog, built on EPA data.
