Other: In the episode 'Anne' Kenn tells Buffy that time in his hell dimension passes more quickly, that one day on Earth is the same as 100 years in his dimension. This means time goes roughly 36,000 times quicker. When Lily falls into the portal, it's at least 10 seconds until Buffy jumps in after her, but Lily is still just sitting there looking stunned. If times moves that much faster, 10 seconds would become over 4 days. Would Lily still have been just sitting there?
Revealing: When Buffy runs in front of the car you can see knee pads on her knees. You have to look quite closely because they are the same colour as her tights. (Time)
Continuity: In the scene where Buffy has just finished fighting the demons, she begins climbing up chains and if you look at her shoes, they continue to change until she reaches the ground above the chains and runs off. (Time)
Continuity: Lily's boyfriend is taken into an alternate dimension, where time moves quicker than ours, and is kept there until he is an old man. But when Buffy finds him, she realizes who he is because of his tattoo - which has not faded or aged in any way. (Time)
Continuity: In the episode 'Anne' when the latest people to be brought into hell are lined up with a demon talking to them, there are 3 or 4 people standing between Buffy and Lily. When the demon asks them all in turn 'Who are you?' we see him asking Lily and after that the shot rests on Buffy, but in the background we only hear him ask one more person before he gets to Buffy.
