Hmm, I think I hijack this thread a little ...
Back in the early nineties I remember watching some japanese live action show sometimes very early on Saturday mornings. It featured I think a policemen, and he and his car could morph (he in a supersuit, the car by lots of body panels switching on hinges, unlike Transformers) The car was white in normal form, and red-ish in superhero form, and its model was something like a AE86 or Supra Mk. II, definitely something with pop-up headlights.
There were toys available, I once found a toy version of the hero car while working in a kindergarten, but somehow didn't check it for the series name.
Any ideas? Its just a nostalgia thing
