Wish: It is very usefull to change the makers_and_models.txt file in the administrator in the vehicle manager instead of uploading a file with ftp. Or maybe, much better, just develop another functionality (just add a maker and model by typing and save when editing a vehicle. Uploading a txt file with ftp is not the way a cms is meant to be. In my vision this must be a high priority to make the extension more attractive to users who are not familiar with ftp. I know how to make a hardcore hack, but when there is a update of the extension the hack will be overwritten as far as I know. So that's no solution.
