I can be contacted via the blender market messenger, or by email at noodlekingdesigns@gmail.com. I will try to get back to you as soon as possible.

Absolutely. Every piece of external data has been packed into the .blend files. Any modifications you make to the file folders won't affect the contents of the .blend file.

The GT40 wasn't made for exporting to other programs. It is entirely possible to export to other programs, but results may vary. I've included a separate textures folder that contains every required UV map and image texture that corresponds with the model.

• Open up the  .blend file
• Select the parts of the model you wish to import to your scene
• Simply press Ctrl+C on your selection, tab into your scene, and press Ctrl+V.

The GT40 is a high poly model. It has around 400,000 faces with all details included. Without the engine or interior, it has around 240,000 faces.
