It’s a little bus that looks cute, but is no longer available for sale. In the vault as they say. From the blurb:
A magic bus trundles down a twisted road, painted and outfitted with the luxury that curious citizens have come to expect from their public transportation: velvet and brass seats, parquet floors, pressed tin ceilings, half-paneled sides, hand-loomed runners, all surrounded by shiny chrome and bright paint. The road travelled is paved and painted with wavy stripes, the better to confuse traffic—a perfect foil for the eccentric Curious Bus Stop around the corner.
