I listed cars as something you should never buy new, but this is not a battle I want to fight. His mind is made up: he'll buy a new car with zero miles on it, and he'll drive it for at least 100,000 miles. Happily. Great. That's fine with me, but one thing that really interested me was his thought process. He thinks about things rationally and doesn't have any particular affinity toward a brand or model.
He has made up his mind about one thing, though, and it's a seemingly small decision that will save thousands of dollars over the lifetime of the car.
That one decision? He's going to buy a 4-cylinder car. This got me thinking.
How Much Money Can You Save by Opting for a 4-Cylinder Car?
For this math exercise, we'll need to make some assumptions. I'd like to stick with arithmetic and stay away from the "you never know when you'll need this in real life" advanced Calculus.
