Well done. I renamed the brands but re-tagged all the cars to "group 5." I always search with the tag feature. This is a perfect for those who like to search by series.
The Porsche 935 1978 version has "1977" as the description in the UI file, so it will appear as two 1977 cars in CM. Maybe you can correct it later, I just fixed it myself in the file.
Thank you so much for fixing the fantasy names the DRM Revival Mod team had to use. This gives back so much immersion and it's so easy to switch between vanilla and real names depending on which server you want to race on - great job !
