Tesla Inventory Helper

Highlights Tesla inventory cars matching configurable VIN rules.

🔋 Find the HW4 Tesla you actually want, faster. Three-year leases from 2023 are ending now, and a large wave of pre-owned Model Ys is entering Tesla's used inventory through 2026. For buyers who want a Hardware 4 car — the only path to future Full Self-Driving upgrades — the catch is that HW4 status isn't shown anywhere in the listing. It's encoded in the VIN: build plant, year code, and production sequence number. Scrolling dozens of listings and reading every VIN by hand gets old fast. Tesla Inventory Helper highlights cars whose VINs match rules you define, so the matches glow on the page as you scroll. No more cross-referencing spreadsheets — the right cars light up. ✨ What it does Adds an animated amber glow around any car on tesla.com/inventory/... whose VIN matches one of your rules. Shows the matching rule's name as a small pill above the card, so you know why it was flagged. Works on individual order pages too (tesla.com/<model>/order/<VIN>) — the vehicle summary glows when the VIN matches. Re-evaluates automatically when you change filters, sort order, or the page re-renders. 🛠️ Configurable VIN rules Click the toolbar icon to open the popup. Rules are written as a small JSON list — each rule has a name and one or more conditions that must all match. Multiple rules are evaluated top-to-bottom; the first match wins. Two condition types cover the common cases: Character comparison — pick any position or substring in the VIN and compare it against a value with ==, !=, <, <=, >, or >=. Numeric comparison — parse a trailing range of VIN digits as an integer and compare it against a number with the same operators. Sensible default rules ship with the extension to flag the typical HW4 patterns out of the box. Edit them, add your own, or restore defaults from the popup any time. 🔒 Privacy No analytics, no remote servers, no data leaves your browser. Rules are stored in Chrome sync storage so they roam with your Chrome profile. The extension only requests permission for tesla.com/inventory/* and tesla.com/*/order/* URLs. ⚠️ Disclaimer This is an independent third-party tool.
