CarPeriscope — Used-Car Watchlist & Buying Copilot

Save any used-car listing to one watchlist. Track price & relisting, compare the market, and get AI help negotiating the deal.

Shopping · English

Car buying is stressful and adversarial — CarPeriscope puts a knowledgeable friend in your corner.

Save any car you're looking at — on a marketplace, a classifieds post, a dealer's own site, anywhere — to one clean watchlist with a single click. CarPeriscope keeps a permanent record of each car (photos and all, even after the listing comes down), tracks its price and days-on-market over time, and flags the games: price drops, relistings, and cars quietly sitting for months.

For any car you're serious about, CarPeriscope helps you close it well:
• Fair-value read and comparable listings — see where the price really sits vs. the market.
• Vehicle report — title/1-owner flags and open safety recalls.
• "Talk it through" — an AI co-pilot that knows this exact car and coaches you on what to offer, what to ask, and what to watch for.
• Draft a written offer and ready-to-send messages to the seller — you review and send.

No account key needed in the extension — just sign in once at carperiscope.com. Free to track your first few cars; the Co-pilot plan unlocks unlimited cars plus the negotiation tools.

CarPeriscope is a buyer's advocate. We send you to the seller's listing — we're on your side of the table.

CarPeriscope extension lets a user save the used-car listing they're viewing to their CarPeriscope watchlist, and keeps saved listings' prices and status up to date, so they can track and compare cars while shopping.
