I have been scratching out a little Windows app/utility for setting the allowed places for cars easily. It will parse the cars directory, read all the configs in the subdirectory, and generate checkboxes to toggle their availabilty for Salon, Shed, Junkyard, or Auction. Obviously it's more for the players that wouldn't have an easy time just manually going through the text files.

I'm open to any suggestions if anyone can think of something else that would be handy to have in such a utility.

Aug 11, 2017 6pm Update: The dropbox DL and github source have been updated with the newest version of the code. There is no longer a need for an "apply" button, changes are saved automatically. There are now buttons at the top for "All" or "None" for the 4 different areas.

Aug 13, 2017 Update: Now with value adjustment! The UniqueMod attribute allows you to adjust the value of the car and probably other mechanics of the game.

Aug 17, 2017 Update: Upper bound for Uniquemod raised to 999.00. This made a Sakura GT20 worth 2 billion without an engine.

Sept 1, 2017 Update: Thanks to your fellow mod enthusiasts, we have a little fixup regarding filenames. Source and executable have been updated.
