1) You’re bad at maths because you bought a new car
Quite a few of my friends read my blog. Some of them like Wendy* are even on board with the whole save enough to retire really young idea, but maths isn’t her forte as the following conversation should show:
Wendy: Can you believe Bill* just bought that big BMW*. So stupid, he makes less than I do. What do you think it cost?
Patrick: Well it was about 2 years old, so it’s probably worth around R300 000.
Wendy: R300 000! I’d never spend that on a used car. I’d much rather get a new one for that price. What an idiot.
Patrick: Well the minute you drove out of the showroom in a new R300k car you’d lose R60 000. After one year of owning it your total loss would be around R90 000. After a year of owning his used car, Bill would only lose R30 000.
Conversations like that often have a lot of uncomfortable silence following them, especially when Ms want to be frugal bought a brand new (though much cheaper) Kia a few months back.
*Names and even cars have been changed. I’ve learnt my lesson on using even relatively similar examples before.
