Car Sale / Resale Platform
Marketplace for buying and selling cars with pricing guidance and transaction tools.
A place to sell a car privately without the two things that make people give up and trade it in: not knowing what to ask, and not trusting the buyer. It prices the car from real comparable sales, builds the listing, and runs the handover through an escrow partner so neither side moves first.
What a v1 does5 features
- A price from comparable local sales, with the range and the reasoning shown
- Listing built from photos and the VIN, syndicated to the big marketplaces
- Buyer messaging that hides both phone numbers until a viewing is agreed
- Escrow handover through a licensed partner, with title transfer steps
- A paperwork checklist for the state the sale happens in
The market
CarGurus takes around $232M a quarter from its marketplace, mostly from dealers, and draws 30 to 35 million monthly visitors. Carvana earns on the cars it sells. A $29 fee paid by a private seller for each car sold would be a different model from either.

Why this audience
This audience is here to avoid being taken - the content is largely about the expensive mistakes people make around cars and credit. Selling privately is where those mistakes are most costly and most avoidable. A defensible price and a safe handover is the whole promise they already respond to.
Before it can launch
- Escrow through a licensed partner; no dealer licence while we never take title
How the pricing works
A listing fee charged once per car sold. A subscription would be cancelled between cars, which is most of a decade.

Opens on the price this idea was costed at, $29.
A quarter is one purchase every four years; twelve is monthly.
1,000 paying — 0.056% of 1.8M followers — × $29 × 0.25 purchases a year = $7,250 a year
Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.
