Extreme Repair (Qiji 4203)

About this set

This KEEPPLEY 4203 Extreme Repair sits in the racing series, boxed as Mine City 极速抢修 with 423 pieces and a 2/5 difficulty rating, aimed at ages 6+. The build is a race pit scene rather than a lone car: a sports car plus a repair station, minifigures and signage, colored in blue, yellow, white, red and gray, so it reads as a small display scene on a desk. I'd suggest building the station and sign first to lock the base and post positions, then the car, then place the figures last so you aren't reaching into tight gaps. At 423 pieces split across modules, the steps stay short and the 2/5 rating means few tricky subassemblies, which suits kids moving from single vehicles to scene building. Three minifigures are included and spreading them around the station and car gives the scene more life than a bare car. Note the box brand reads 启集 while the product name is Mine City 极速抢修, so check the version before buying. This is a display-and-roleplay set, not a mechanical showpiece.
