•The engine you build is a greatly simplified version of a real car engine. The model is designed to be fun to put together, and to make it easier for you to understand how a full-size four-stroke car engine works. This box contains all the parts and tools you need to assemble the working model.
This has been reduced by a fiver to 14.99. There are other retailers and eBayers selling what looks like the same model for 24.99.
Unless anyone can tell me there are 2 versions of this kit? Looking at some of the images on a google shopping search, there are some that look different to others (different box colour and engine style). The descriptions all sound suitably similar.
