Continuity mistake: When the baddies make a hole in the wall to grab the money, the size of the hole, the hanging parts of the wall and the protruding isolation foil change between one shot and another without no-one having touched the wall. (01:14:40)
Continuity mistake: Brian stops racing and Suki arrives next. She places her arm over the windshield but a shot later her arm is gone. (00:14:01)
Deliberate mistake: The relay drag race takes much longer to complete than it should. Each leg is a quarter mile going and back, the cars involved should be able to make their runs in much less time than is shown. Brian even tells Roman that the Yenko (the blue Camaro) can do a quarter mile in 5 seconds flat, but it still takes ten times that long to complete the entire run.
Continuity mistake: When Brian Roman arrive at Tej's garage after meeting with Verone at the club, Tej, Jimmy, and Suki are playing cards. There is a shot of them at the table and then an overshot view showing clear solo cups which appears to have beer in them. But after Brian gives Suki a kiss, then next shots show red solo cups on the table, not clear.
Continuity mistake: When Verone and Monica meet up with Brian before they get on the boat, in the background one of Verone's men walks up the dock and stops at the beginning. When Verone tells one of his men to put Monica on the boat, next shot cuts to Brain, and back to Verone. The guy at the beginning of the dock is not there but midway down the dock. It then shows him walking up again when Verone points the shotgun at Monica.
Answer: The blue car with the white stripes is a 1969 Chevy Camero with a yanko engine. The orange one is a Dodge Hemi Challenger.
