Something strange is afoot

So I am walking into my apartment building and I see this red caddy illegally parked, obviously waiting for someone. As I approach, the young man standing next to the vehicle opens the door for 2 guys who are most definitely his peers (at least age wise), then closes it after them. They do not appear to be the type to have a car let alone a driver. Strange. And what is even more strange is I think I saw this very same vehicle a couple weeks ago picking up a young women who was um, dressed a bit, uh, risque. Not the same driver, I might add.
