Understand the car and the deal — before you sign.
PattyKnows helps you compare cars, decode a dealer worksheet, and figure out what actually matters to you. Independent from dealers, in plain English and Spanish.
PattyKnows is independent buyer-advocacy education. It works for you, not for any dealer. It is not a registered, bonded, or licensed automobile broker, and does not negotiate, arrange, or complete a purchase or lease for you.
How PattyKnows helps
Compare the car
See the trade-offs between real options — pickup, safety, winter capability, cargo — scored against what you said matters.
Decode the deal
Turn a confusing dealer worksheet into a clean Deal Sticker with the true monthly cost and the fees that are just padding.
Understand what matters to you
A few trade-off questions build a preference profile you can edit anytime. It hears you instead of selling you.
Ask better questions
Walk in with the exact questions to ask and the red flags to watch — so nothing gets slipped past you.
Three tools, free to use
Built from the buyer's side of the desk. No account, no uploads — nothing you type is stored on a server.
Find your fit
A few trade-off questions build your preference profile, then rank real options against what you said matters.

PattyKnows works for the buyer. No dealer pays us, no dealer referrals, no lead sales, no “preferred” anything. The only side we're on is yours.
Who's behind it
Patty spent 25 years inside car dealerships. Now she's on your side of the desk — turning what she learned into tools any buyer can use, in English and Spanish.
Start with what matters to you
A couple of minutes of trade-off questions, and you'll see options ranked to fit your life — not a dealer's inventory.
