The model is great, overall nice to look at. It doesn't include many functions, except motorization, but that's fine since it allows the model to work properly as it doesn't try to pack too much stuff. The electroplated pieces are a nice touch, and the motors are nicely packed into the model. I feel however that the battery pack is in the way of the engine cover on the right side, so that it doesn't close properly and doesn't sit as flush as it should. I love the rims with the red line all around them, I feel it is an easy way to embellish this model without adding complex stuff. I've chosen however not to include the original stickers as they don't look so good to me.
The only other function outside of motorization and the obvious ones (suspension, steering, doors) is that you can adjust the rear diffuser. This function is a bit tricky to operate and I feel that the pieces are a bit stressed in the way the mechanism is built, but works fine in the end, so it's ok. In one of the pic the model is side by side with another white 1:8 car from CaDa for comparison.
