Instead of lying on your loan application, adjust your budget to fit your needs. While you might want a brand new Mustang, there’s no shame in getting something in your price range. You won’t have to lie on your application and you won’t stretch yourself too thin financially.
If you’re already stretching yourself too thin on a car note, don’t forget that you need full coverage car insurance. This type of insurance can often cost as much as the car payment itself, so you need to budget for both expenses.
