  🔋 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.

  🔋 Find the HW4 Tesla you actually want, faster.
  
  A wave of pre-owned Teslas is entering the used market as 2023 leases come back through 2026. If you're shopping specifically for a Hardware 4 car — the only path to future Full Self-Driving upgrades — there's a problem: HW4 isn't labeled anywhere. You have to read the VIN. On every listing. Manually.
  
  Tesla Inventory Helper does the reading for you, wherever you shop.
  
  ✨ On Tesla.com
  
  A soft amber glow lights up the cars that match what you're looking for as you scroll, so the right listings find you instead of the other way around. Works on Tesla's used inventory and order pages, in any country. Comes pre-configured to flag HW4 cars, and you can tune it from the toolbar popup any time.
  
  🚗 On popular third-party car-listing sites
  
  When you land on a Tesla listing on a supported third-party site, a small dark panel appears in the top-right corner showing what the VIN actually means:
  
  What it is — Model S, 3, X, or Y
  What year it really is — verified against the VIN, not just what the seller wrote
  Where it was built
  Roughly where it sits in the production run
  Whether it's likely HW3 or HW4
  
  No more wondering whether a "2024 Model Y" is really a 2024, or whether a used listing is the HW4 you've been hunting.
  
  🔒 Private by design
  
  Everything runs locally in your browser. No analytics, no servers, no tracking. The extension only reads pages on Tesla.com and a small set of car-listing sites — Chrome will show you the exact list when you install.
