What is CarSmarts?
CarSmarts is a desktop Chrome browser extension that enhances your car shopping experience on carsales.com.au. It automatically tracks listing prices, detects changes, and shows you insights that help you negotiate better deals.
Unlike other tools, CarSmarts is powered by crowdsourced data from all users. The more people use it, the smarter it gets.
Crowdsourced Advantages
Price Drop Alerts
See when a listing's price has dropped since it was first seen. Spot motivated sellers and negotiate from a position of strength.
Listing Age Estimates
Know how long a car has been on the market. Older listings often mean more negotiating room.
Stamp Duty Calculator
Instantly see the true drive-away cost with stamp duty calculated for your state, right on the search results.
Price Change History
With more data and more users, price change history becomes visible even for Dealer listings!
Personal Notes
Add private notes to any listing. Keep track of your thoughts, inspection dates, or negotiation points.
Community Data
Every user contributes to the collective intelligence. More users means better data for everyone.

Join the Development
CarSmarts is currently in alpha development. It is missing a lot of useful functions that are best added with the help and feedback from regular users. For example: showing Redbook price estimates, logging and searching Facebook Marketplace ads, or maybe adding a Safari extension! We're looking for early adopters to help test and improve the extension. Your feedback shapes the product.
The extension is open source and free to use. Install it now and start contributing to the community data pool.
