That's just one of those secrets that you need to know, though. It's like knowing to ignore the unemployment rate (in the vast majority of cases) and instead to look at the prime-age employment rate. People rarely think of something like that without being told.
Cars are also one of those things that can be an emotional purchase and people do weird things. I spent way more than I needed to in order to get the car I wanted and I wanted it because it's a cool vehicle that, when I squint, still fits my needs. It wasn't smart financially but I'm extremely happy I did it. My wife could not care less about a vehicle outside of it being ergonomic and not having a payment. We'll be looking at depreciation curves and the like during that exercise.
