Here is the current Sketchup 8 file by Jeff. I was able to open it in the Sketchup 13 version. The new version allows you to use the “Pro” features for 8 hours. After that, the application still works but if you want access to the “Pro” stuff you have to buy a license.
Please feel free to download it and play with the objects. We are working with Display Car 2 right now. The others are previous concepts.
