This is a nice kit. There is a complete interior but can be difficult to see depending on how the kit is modelled. The overall size of the kit is quite impressive as well. The instructions are clear and easy to follow and there is very little clean up of the parts. The fit of the parts is good. I would recommend this to a modeler that has a little experience because of the tracks. Each track consists of 2 pieces and takes a lot of time and work to clean up and put together.
