Z-1500 only came in blue/white or pink/white. The one on ebay used to be pink, I know because it used to be mine and the bb still has remnants of the paint inside it. They were late production Pro Motion frames with Spinner forks.
People still need to remember that paint & decals are not indicative of a bicycles origin. Many an ebayer claims his POS is a GT because the sticker says so.
