Automotive Purchase Decision Framework

Buying a car is something many of us dread.

For most people, it’s the second largest financial decision after housing. Yet almost everything about the process works against the buyer. The dealership system is designed to confuse. Prices are rearranged, rates are shifted, and numbers are moved around until the outcome seems favorable. That said, it rarely is.

Due to my sheer disdain for dealerships and car salespeople, along with a need in the family that arose, I created an automotive purchase decision framework. It provides a platform to evaluate tradeoffs and the opportunity cost of whatever decision you make.

The reality is that every time we walk into a dealership, we lose something. Dealers know how to separate emotion from reason, and they use that gap to their advantage. They play with the levers that matter most to them, not to you. They are not on your side.

The goal for many of us should be to spend as little on automobiles as possible. We want something safe and reliable, but they are depreciating assets that begin losing value the moment we drive them home. But because transportation is essential, we do have to make the occasional car buying decision. The best we can do is to make informed, intentional choices that limit how much we lose.

I constructed the Automotive Decision Framework to help with this process. The tool allows you to compare multiple offers side by side and understand the full picture. It calculates total interest paid, if financing, identifies breakeven points between rebates and lower interest rates, shows how extra payments change payoff timing, and incorporates depreciation so you can see how much of your money stays tied up in something that is constantly declining in value.

The goal is not to tell you what to buy, or not to buy. It’s to help you understand the tradeoffs so you can come to your own determination that aligns with your goals.

Remember, car buying is emotional by design. Dealers rely on that. The more complex and hurried the process feels, the more likely the buyer walks away having paid too much. Clarity removes that power. When you know the numbers, the leverage shifts.

A good deal doesn’t come from pressure, or from the excitement of signing papers under bright lights. It comes from knowing your numbers, your limits, and your alternatives before you ever set foot on a lot. The less they can confuse you, the more likely you are to keep what’s yours.
