"This Lego set along with the other Speed Champion sets make an excellent addition to the Lego themes. The build is interesting with many smaller parts which add considerably to the detail. The stickers can be a challenge requiring a steady hand to apply. The wheel fixing, unfortunately, results in too much friction to allow the cars to run freely! What would further enhance the appeal of this set would be a race track based on a curve and a straight section and possibly barriers on the outside of the curve."
