The guideline check

A common rule of thumb keeps all vehicle payments inside 10 to 15 percent of monthly take-home pay. A guideline, not advice.

The green zone is under 10 percent. The gold zone is the 10 to 15 percent guideline band. Past that, the payment starts steering the budget.

The honest part: A car is a depreciating asset. Most vehicles lose a large share of their value in the first few years, and a long loan means you can owe more than the car is worth for much of the term. Stretching the term to shrink the payment does not make the car cheaper. It makes it more expensive and keeps you underwater longer. The total cost number above is the one the dealership never leads with.
