The best inventory is gone in hours.

Auction sites, classifieds and private-party listings in one feed.
Checks run around the clock, not when someone remembers to look.
Alerts land while the seller is still answering their first call.
Three steps, then it runs itself
Set it up once. It keeps working while you sell cars.
Pick your city
Choose the market you buy in. The free plan covers one city — add more when you are ready.
Describe your buy box
Type it in plain English: "clean-title German sedans under $40k, no salvage, under 80k miles." No forms to wrestle with.
Get told first
Matching listings land in your dashboard as they are posted, with price, mileage and a direct link to the seller.
Built for the people doing the buying
Auction fees, transport, and reconditioning all come off the same margin. Buying direct from private sellers avoids most of that — the hard part has always been finding those cars before somebody else does.
That's the whole job CarGriddle.com does. It watches continuously, filters to your criteria, and skips the dealer-posted inventory you can already see.
