A few things to know.
Can I subscribe just while I’m car shopping?
Yes. Choose monthly or yearly, then cancel whenever you’re done. You keep Pro until the end of the period you’ve paid for.
Do both plans include the same features?
Yes. Monthly is $15, and yearly is $150. Yearly saves $30 compared with 12 monthly payments. Each plan renews automatically until you cancel.
What stays free, and how fast are Pro alerts?
Daily and weekly alerts stay free. Pro adds recorded price history and real-time alerts, sent as new matches or price changes are found. Timing depends on when a source publishes a change and our next update; it isn’t a continuous live feed.
How do I cancel or update my payment details?
Open Billing from your account, then Manage subscription. Stripe handles cancellation, payment details and invoices securely.
Will every VIN have a window sticker and full history?
No. Coverage depends on the car and the records available to us. We show what we have and distinguish asking prices from sale results. Always confirm the car’s condition and details with the seller.
