In the 1964 flashback scene where Manny is pulled over by police, one could see the front end of a 5th generation full-size Chevrolet (Impala?) with a hubcap from a 1980-85 Chevy.
During the party scene at Kilo's house, music is being played. This is supposed to be the late 1970s but instead of using music from that era, modern techno music is heard.
