In "Hit and Run", one of the hired assassins blows up the Porsche Nash was loaned until the 'Cuda is fixed. When Nash tells the owner about this, he says "It's just a car. Don't cry." This comes across as somewhat hypocritical given how much Nash cares about the 'Cuda. However, it's not. While the Porsche was just a mode of transportation to its owner, the 'Cuda is Nash's link to his missing brother Bobby.
A Running Gag in season four involved a "phantom disco" in the unit's headquarters (a former nightclub) that would come on without explanation or warning. This "disco" would include strobe lights. It's a good thing this was taken care of in season five because Antwon (an epileptic) showed up in season six. The poor guy would have had a seizure every time the strobes came on.
