Overview

Read the car listing in this tab and value it from real completed sales.

Shopping for a car online? Before you bid or make an offer, find out what it's really worth. Open a car listing, click BidBetter and press **Read this listing**. BidBetter reads the year, make, model, miles and VIN from the page. It then finds completed sales of the same car in BidBetter sales data and shows you a value range based on them. **WHAT YOU GET** • A "most likely" range and a full range, adjusted for mileage and year • The completed sales behind the number, so you can check every one • A confidence badge that tells you how tight the data is. If nothing close sold, BidBetter says so instead of guessing • Live auctions: in the final hour, the current bid blended with completed sales, plus the price with the buyer's fee • A walk-away price for auctions, with the buyer's fee already added • Dealer and classified listings: the asking price next to what the car actually sold for • A VIN decode from NHTSA • A summary of the seller's answers and the comment thread on auction sites **VALUE A CAR WITHOUT A LISTING** Enter a VIN or the car's details on the Value a Car tab. **MY GARAGE** Save the cars you own and check what they're worth. **SAVED REPORTS** Save any read as a report, then export it as a PDF, print it, email it or send a share link to a lender or partner. **WORKS ON** Major online car auction, classified and dealer listing sites. **PRIVACY** The first time you use BidBetter on a site, Chrome asks for access to that site only. Nothing is read until you allow it. **PLANS** Free accounts include 3 lookups a month, 3 saved reports and 1 garage car. Paid plans are unlimited. BidBetter gives an estimate based on past sales. It is not an appraisal or an offer.
