Here’s the skinny on buying a car. I realize that nearly every personal finance book out there will tell you that buying a car is the worst financial commitment you’ll ever make. Cars depreciate fast and consume significant resources due to use and maintenance. Yet we all dream of one day owning the noisy muscle car (I do, at least), the Italian sportster, or the tricked-out minivan with 12 DVD players. So, should you skip the car altogether? If you don’t have the money for one, perhaps. But if you can afford a car and need one for your job, you should consider getting one.
