If you want a more meaningful result, I think you need to have $100k increments up to $500k, then an above $500k category. M3 is not a cheap car, nor is it the only car for a lot of people.

There is also the fact that people are willing to spend very different percentages of their income on a car. I personally think it is ludicrous to spend more than you annual gross income on a car, yet it seems some M3 owners are doing just that.
