Mobile Racing Center (Qiji 4204)

About this set

This KEEPPLEY 4204 Mobile Racing Center sits in the Mine City line, with 1095 parts on the box, a 6+ age mark and a 2/5 difficulty, so the build load stays light and leans on scene and vehicle play. The palette is red, white, green and grey, built around a gas station and repair shop building, plus a red sports car and 5 minifigures; the repair bay and air pump lines give the pit scene some real structure, and the selling point is transforming into pit mode. I would build the main building and repair bay first, then add the air lines and the car, since routing the lines and lining them up with the bay are the steps worth slowing down for. Test the transforming structure as you go rather than after the roof goes on. At 2/5 with 1095 parts it suits builders aged 6+ moving up to a larger set, and anyone who wants a switchable racing pit scene for minifigures and a car.
