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