Some more info:
The carrera buildings are modular so you can combine them as you wish e.g. your control tower can be as high as you wish and angled in the direction you want. The grandstand can be added to with a separate lower part - makes it twice as tall.
Figures are revolving with movable parts of the body, are detailed and coloured. According to the Carrera Catalogue they are to be sold in the following packages. Set of figures, small (5 figures - 3 sitting and 2 standing). Set of figures, big (15 figures - 12 sitting 3 standing). Set of figures, grandstand (20 figures sitting). Set of figures, mechanic (5 figures).
They are expected sometimes in late summer / autumn. I have not seen any prices yet.
