Why list on LemonChecks?

The only AI-indexed car market

Most car sites block AI. LemonChecks shares your post with all major AI chatbots and assistants, so buyers asking them for a car can find yours right away.

Instant VIN & recall check

Every car is decoded with NHTSA data and checked for model-year safety recalls the moment it is listed.

Private direct contact

Emails and phone numbers are never shown to people or AI. Lemmy relays messages, and you choose who gets your contact info.

Zero listing or dealer fees

Post free with just your email. No password, no dealer markups, no spam calls.

Posts marked "Sample post" show how the boards work and can't be messaged. Title status is reported by the seller; always run a full VIN history check and get an independent inspection before you buy.

Built for AI agents

Every post is searchable by ChatGPT, Claude and other AI assistants

LemonChecks offers an MCP connection so AI car-hunting agents can find your car or your request. See how it works →
