Private-party car deals, found first
CarDealBoss watches eBay Motors, the private-party market, and Facebook Marketplace around the clock. It prices every car against live market data and texts you when one posts well under its value — then writes the negotiation messages. You just reply YES.
Free tier at launch. No card required.
How it works
Good private-party cars don't sit. By the time you're scrolling after dinner, the one priced under market has already met its buyer. CarDealBoss compresses your reaction time from days to minutes.
eBay Motors and licensed private-party listing data run on our servers around the clock. Facebook Marketplace runs through a companion in your own Chrome — your login, your browser, your rules.
Each car is checked against live market data — VIN-decoded when the VIN is listed. Every estimate is labeled with its confidence, so you know exactly how much weight to put on it.
When a car posts under your threshold, your phone buzzes with the deal and a ready-to-send opener. Approve each message with one reply. Your maximum price is a hard ceiling the assistant can never cross.
Why speed pays
Default deal threshold — only cars at least this far under market reach your phone.
Fastest polling cadence on Pro. A listing barely exists before you know about it.
Approvals per message. One YES by text. Nothing ever sends itself.
The boring parts, done right
Deal-hunting tools love to overpromise. We built the opposite.
The assistant drafts; you decide. Messages to sellers go out from your own browser, under your own account, only after you say so. There is no auto-send switch to accidentally leave on.
A VIN-verified value and a model-level estimate are different animals, and your alerts say which one you're looking at. We never dress up a guess as a fact — and we don't borrow other companies' book values.
Facebook coverage runs in your browser, so when Chrome is closed, it's paused — and your dashboard says exactly that, with a timestamp. The server-side sources keep running either way.
Set your max once. Every draft is checked against it before you ever see it — a draft over your ceiling gets rejected and rewritten, never quietly rounded down and sent.

For reference: established car-sniping tools charge $88–$352 per month for less coverage and no negotiation help. We'd rather price for people who buy one good car a year, not just full-time flippers.
Questions, answered straight
No. The assistant writes drafts; every single message waits for your approval — a tap in the dashboard or a YES by text. Messages go out from your own browser under your own account.
Through a Chrome extension running under your own Facebook login, on your machine. We never hold your Facebook credentials and our servers never touch Facebook. When your browser is closed, Facebook coverage pauses — and we tell you so instead of pretending otherwise.
Live market data: licensed pricing on active private-party inventory, plus the running record of comparable listings we observe ourselves. VIN-decoded when the listing includes a VIN. Every estimate is labeled with its confidence level. We don't use or claim any book values.
You set a threshold per search — the default is 15% under market value. Only cars at or past your threshold, at your minimum confidence level, reach your phone. Everything else stays out of your way.
