The walk line

Decide at home the out-the-door number above which you leave, then let that number decide for you.

What to do. Set your walk line before the first quote arrives. If the total at the desk is above it, or differs from what was agreed, leave.

The walk line is the out-the-door price above which you get up and leave. You set it at home, before any dealer gives you a number, and you write it down.

Setting it early matters. Once you've spent an afternoon at a dealership, driven the car and pictured it in your driveway, every number starts to look reasonable. The walk line is a decision made by the calmer version of you, at the kitchen table, for the version of you sitting at the desk.

A sensible walk line sits below your affordability ceiling and close to your best real quote. Say the app shows a ceiling of $34,000 out the door, and your best written quote is $32,900. You might set your walk line at $33,500. At the desk, the total comes back at $34,200, with a fee nobody mentioned before. That's $700 over your line, so you thank them and go. No debate needed.

The walk line also covers a deal that changes. If the numbers at the desk differ from what a dealer confirmed in writing, that alone is a reason to leave, even if the new total is under your line.

Leaving doesn't have to be dramatic. Sometimes a better offer follows you home, and sometimes it doesn't. Either way, the point is the same: you never sign a number you decided against at home.
