As an educational tool, this game is excellent. Accompanied by an instructor who knows what he or she is talking about, a child can learn quite a lot about cars. This game was purchased for me as a five-year-old as a way to channel my interest in cars into a constructive environment. I obviously enjoyed it, preserving it through many disks, then many hard drives, and now I can share it with you. Give it a try. It is a small, simple, and fun game in a unique genre Though its chunky CGA graphics are a bit dated, it still shines with gameplay a-plenty. I've included some "recent" cars of my own, so that you may see what can be done with the game. Enjoy!
Note: the developer Optimum Resources is still very much alive, and updating new versions of Car Builder to boot! Check out the official game site below for the most recent version you can buy :) [thanks to Marc J. for the info]
