The costs include TWO new cars and a ton of other miscellaneous fees. I'm sure that the point being made is valid to some extent, but the calculations are way out of proportion.
There aren't a lot of vehicles which you can buy used, put 95k miles a year, and end up with reliable vehicle 12 months later. You basically trade up initial investment cost vs subsequent maintenance cost.
Also, if he has good credit, I could see how automakers' aggressive 0% financing could result in a lower monthly payment for a new car than a used vehicle (since no one will finance a used car at 0%).
