Alex looks at the one long black luxury car "hiding" at the end of the road but how can someone be able to hide that flashy big car like that? So it was quite obvious and can be seen at one glance.
He then looked back at Jake with lots of thoughts running through his mind. He can tell that the car and Jake have some relation or at least the reason why Jake is here can't be separate from that car.
So his eyes were like a hunter in the wild searching for each and every one in his sight. His priority was a woman as he knows women are the pushing force of the protagonist but there is no one standing out.
No woman nor man, He had given up on the hope of the chances of here being heroines when he did not find her at a first glance as it is impossible for heroin to not stand out in the crowd.
