The damage to the surfers' ambulance (headlight) disappears and reappears.
The brown van has Surfers Rule spray painted on its side in the shows opening chase scene. It is then later spray painted on the van by the surfer dudes.
When Ponch and Jon are scoping out the ice-cream truck, Ponch orders two strawberry popsicles, which cost 50 cents each. The ice-cream man asks for $1, and Ponch hands him a $1 bill. After Ponch and Jon receive their wrapped popsicles, they unwrap them, but instead of strawberry popsicles with two sticks each, they have been given Bomb Pops, which only cost 35 cents each.
When the brown van rolls over, there is a mannequin in the front passenger seat.
During one scene where Jon loses pursuit in a chase, he misidentifies an early 1960's Ford Van as a late-model Chevy Van.
After the surfer dudes spray paint the van, the two vehicles take off, with them being described as heading on the PCH Northbound. However, with the beach on their right, they would be heading southbound.
