Not sure if Daz and Ste will find this useful but i will
If you were on track can you post here what car you were in and if not that unique (S14a for example) the last part of your reg or a stand out feature (white wheels etc)
I have most people but have no idea on most of the drift cars and a few that were on the grip track (the 2 silver M3s for example)
I will put some here off the top of my head then add as you post.
