"I see by the license plate that you are in Bogota. Are Porsche cars common there?"
Bogota = Drug capitol of the world.
Drugs = Lots of cash
Lots of cash = lots of fine european cars. I'm betting there's a huge crowd of Porsches around town!
Cartagena, I'm not implying you're involved in drugs because you live in Bogota... but it does stand to reason that if a guy has an extra 100k sitting around, he might as well buy himself a nice car to drive
