I'm tired of checking out hot models

Here's what I see after checking out hot models for two weeks in my back alley.The chart is boring, and I think that the data is bogus. I do not believe that Autotrader.ca follows what appears to be a near-perfect linear rate of increase in number of hot models. After week 1, I was hoping to observe some interesting trends of increasing supply at mid-week and it falling off approaching and during the weekend (when I would expect an increase in car sales); however, this did not hold true.

I'm bored with these data and don't think that I will be watching hot models from my apartment window any longer.
