Classic example of the Baader Meinhof phenomenon. On Saturday night I was trying to explain this theory to someone and I couldn't remember the name of it or the time period.
That's the one where you buy a car, and shortly thereafter discover that there seem to be more cars of the same model on the road than before.
In reality, there are the same number as before--plus one if you bought yours newly manufactured--but your brain is now primed to notice them more often. Before, they blended in with the myriad of other car models, but now you notice that other people are driving your car.
That's in general but it doesn't necessarily work for that example unless you are talking about a more general classification of a car like a ford or maybe a ford fiesta (do they still make thos? ah the 90's!).
If you just bought a brand new 2016 model BMW 525i there's a good chance that if you start seeing more of them it's because there are actually more of them now. :)
