There are two ways to lose money at a dealership. One buyer walks in with a number they made up and gets nowhere. The other pays whatever’s on the sticker because they don’t know what else to do. Both leave real money behind — usually thousands of dollars.

The Car Deal Maximizer is a 9-step interactive tool built by a former dealership Internet Sales Manager — someone who ran the desk on the other side of this exact conversation. It walks you through your trade-in, your new car purchase, and the finance office, and hands you the real numbers and the exact scripts for each one.

Your trade and your new car are two separate negotiations that dealers like to blend into one confusing number. This tool keeps them apart on purpose — that split alone is worth real money.

Work through it in about 15 minutes the night before you go shopping, then bring your numbers with you. Works on any device, no login required, and you can keep using it right up until you sign.
