Funny thing I have observed... Knowing approximately the prices of real estate in different parts of POP, the vehicles in the poorer parts are usually those recently imported and thus more expensive CRVs you name it whereas many times (not always) in residendial areas the vehicles are much more "humble" in a way... Our neighbors, who are expats and entrepreneurs, drive with a smaller end Ford/VW/Kia, for example... Then again, they are expats so exactly what you posted regarding cultural differences...
Then again, back when we lived in a barrio, I witnessed people living in very poor conditions to drive new CRVs etc without any plates... Then the cars disappeared...
