All right, thank you !
Very good product. Plastic parts are really well made, no defects, no complaints about its quality. It came missing 3 small parts, but they were replaced for other 4 similar ones that came additional. But this kind of issue I also found in Lego products as well. It has a working differential, engine that can be engaged or disengaged with a gearbox-like-lever and also a crown-pinion assembly to turn the wheels. The manual of instructions is Lego like, nothing missing, colorfull and well made. Just the stickers were not very well cut and the glue left its marks, but that's ok. My girlsfriend and I had a lot of fun building it. Looking forward to buy the next ones.
