Agree with all comments above but have no idea how the song relates to the car choreography, or indeed cars?
Unless, of course, when he is referring to ‘save your tears for another day’ he meaning the impact of parts and workshop costs that can bring tears to your eyes when talking about ‘older cars’. But he is saying to save your tears for another day, as enjoy the driving the car and not think what it’s costing you, you can worry about that ‘another day’
Maybe I’m just reading too much into this, or have too much time on my hands!!,
