I would like to add that in my opinion the car's name is not Ruse04. I think I know where did you ge the information from (the file is signed as ruse04stoyanstoyanov2, right?
). I believe in the file's name Ruse is just a reference to Ruse University, 04 - to year 2004, Stoyan Stoyanov - obviously to designer's name, 2 - number of this car's photograph
