Overview
Auto-fill Facebook Marketplace listings from AutoTrader, CarGurus, and Cars.com. Posts a car in about a minute. Requires an account.
Post cars to Facebook Marketplace in one click — straight from AutoTrader. Avarus is a Chrome extension built for car dealership salespeople. Open any vehicle on AutoTrader, click "Post to FB," and Avarus fills the entire Facebook Marketplace listing automatically — photos, price, mileage, description, condition, and location. No copy-pasting. No re-uploading photos. No switching tabs to manually retype specs. WHAT AVARUS DOES • Auto-fills Facebook Marketplace car listing form from AutoTrader data • Downloads and uploads all vehicle photos automatically (blob transfer — no broken image links) • Generates AI-written vehicle descriptions in multiple tones • Posting queue — add up to 10 cars, run them back to back without clicking anything • Inventory audit tool — detects price/mileage mismatches between AutoTrader and your Facebook listings • Sold detection — flags cars that have been marked sold on AutoTrader • FTC compliance monitoring — alerts when listing data looks out of sync • Price adjustment buffer — automatically adds or subtracts a set dollar amount at post time • Smart Model Line detection — recognizes specialty builds (Shelby, Roush, Rocky Ridge, Alpina, etc.) • Location override — post from any location, not just your profile default WHO IT'S FOR - Dealership salespeople who post inventory to Facebook Marketplace daily - Independent car dealers managing their own lot - Anyone who uses AutoTrader and sells on Facebook Marketplace HOW IT WORKS 1.
