Yeah, I am firmly in the camp that would love to have a redo of Tracks. I transformed him a grand total of one time, then left him in flying car mode for all eternity. It doesn't look great in this mode, which is a shame, because I always thought it was one of Tracks' best features. But it's just that his arms are chillin' by his sides, and half of the vehicle's side is "missing", due to the empty cavity where the arms should be in car mode.
I want to like Kingdom Tracks but he gets in his own way too much to be enjoyable, and the end result is not terribly aesthetically pleasing. In another 8 or 10 years, maybe his card will be pulled for an update. For now though, Kingdom Tracks will remain in his doofy little flying car mode, never to be handled until he is put away or sold.
