The model has some steering movement on the front wheels and some suspension movement on the back side (but not the front). The box makes it clear to label the model as "Diecast metal with plastic parts" since it seems that most of the mode is made of plastic with only minor sections made of metal. However, one would have to be very discriminant/observant to be able to differentiate where the metal ends and the plastic starts. These models are really well made and at this level of finishing and detail, it is quite irrelevant what the material is when the overall model is so realistic.

From my experience with Welly car models, I was expecting a high degree of detail and quality. Headlights, taillights, engine details, brake lines, exhaust pipes, etc are all very realistic. But what caught my attention were the various warning signs at various locations of  the model, those really took realism to another level.

The wheels are made of rubber and made is a way that it feels like having low pressure, just like the real deal. The wheels can roll very smoothly so be sure of how you display these models. I say this because if you are not careful it will roll off an uneven table/shelf, and these things will not survive a fall.

Keep in mind that these are really not toys and will not last long if played with regularly. These will definetly not last long if given to a child of a spin on the sandbox or back yard.

These models come in a window box. The box is labeled as "Not suitable for children under 3" but I would say 14 (years) sounds like more realistic (as other models are labeled).

The box measures 9" x 5" x 5"
