The car Johnny gets from Daniel is a 2008 Challenger R/T, but after it is customized in Cobra Kai livery, it changes to a newer style 2015 - 2018 Dodge Challenger SRT, judging from the gauge cluster, steering wheel, and the updated grill and taillight treatments.
When Daniel LaRusso allows Johnny Lawrence to select a vehicle from his used car inventory at LaRusso Auto Group to replace Johnny's 1991 Firebird, accidentally destroyed by Daniel's cousin, Johnny selects a 2009 Dodge Challenger R/T Classic. In a later episode, Johnny has the Challenger repainted in his black and yellow Cobra Kai motif.
However, the repainted Challenger is not the 2009 R/T Johnny received from Daniel, but rather an 2015 - 2018 model as evidenced by the updated grill and taillight treatments, as well as the driver's side instrument cluster.

It is impossible to enter a (functional) cement mixer through the business end, or stand and walk inside them, as cement mixers have a spiral paddle running down inside them, which helps with the mixing. The shot from "inside" the mixer is obviously made in a modified tank, and not a cement mixer.
The platform on which Robbie and Samantha balance clearly isn't actually floating in the pond, as several shots reveal that the platform is stationary.
When Robby and Samantha first get on the wooden platform in the pond, they are supposed to be balancing each other out. Yet when they perform their moves, they are opposite to each other, but to the same side of the platform, including when they turn to the side. This move would unbalance the platform, as both of their weight is now on one side of the platform. Despite this, the platform does not tip to the side.
When Johnny removes the LaRusso tag, he doesn't unscrew it but simply pulls it off.
