<prompt> Human: Ill spare you the details of my upbringing, but only now, at the ripe old age of 36 have I finally gotten a grasp on my finances; thanks in large part to this sub. Ive been using YNAB for the past three months, and am _definitely_ better off than I was before.Interestingly, just yesterday I found out about the 110th rule for buying a car. That is, you shouldnt buy a car that costs more than 110th your annual income. I gross 70kyr, so I could definitely get a 7k car to get me around. But Im curious as to how many people here follow that rule? Im EAGER to increase my wealth over the next few decades and Im willing to do what it takes.Im just thinking, I know my boss makes 120kyr. And hes driving a new Mercedes. How do people do this?Also, how much weight would you put into the area of the U.S. you live? 70k in ATL where I live is pretty good, but that same amount in, say, New York would be paltry.  <response>: This isnt a rule that a makes sense or b people follow.
