Web Pros / CarPeriscope
By Web Pros · Free, Co-pilot $12/mo
Car buying is stressful and easy to get burned on. CarPeriscope is the buyer's advocate: save any used-car listing from any site to one watchlist, then watch the price and the seller's games over time — and see below the surface with tools no listing gives you. On your side of the table.
A free Chrome extension + web app. Upgrade only when you're serious about a car.
The problem
A car gets relisted higher, quietly price-dropped, or pulled the moment you hesitate — and you're left with browser tabs and a gut feeling. CarPeriscope keeps the receipts: every car you save is tracked forever, photos and all, so you see what's really happening before you spend real money.
How it works
See a car on any listing site — a marketplace, a classifieds post, a dealer's own page — and click the extension. We keep the photos, price, and details permanently, even after the listing's gone.
One watchlist tracks every car's price and days-on-market over time, and flags relists, slow drops, and scam red-flags automatically.
Dig deeper with recon, photo inspection, comps and a full VIN history — then get a suggested offer, your walk-away number, and a drafted message to the seller.
No dealer money, no lead-selling. CarPeriscope answers to the buyer, full stop. Free to start; Co-pilot is $12/mo, plus pay-as-you-go credits for the heavy-lifting services.
What you get
The stuff that actually protects a buyer — see below the surface before you commit.
Every car you're considering in one place, tracked over time — price, days-on-market, and permanent photo snapshots that outlive the listing.
Reads any listing into clean facts and flags the seller's claims and common scam signals the moment you save it.
Searches the whole web for a car's VIN and shows everywhere it's appeared — catching cross-site relists and price games.
Reads the listing photos — odometer off the dash, visible damage, mods, and window-sticker details you'd otherwise miss.
From the car's location: road-salt/rust-belt exposure, coastal salt-air, flood and hail risk — and exactly what to inspect.
Comparable listings, a fair-value read, and an AI co-pilot that suggests an offer and drafts the message to the seller.
