In "Gone in 60 Seconds," they refer to Eleanor as the "unicorn" because something always goes wrong with the Shelby GT500 around. In my opinion, the TDU modding equivalent of a unicorn is the Porsche 911 GT3 RS.
This is just something I noticed - no need for people to start saying "Make pls pls pls!11!!!11" or for T3hReaper to Get Angry And Capitalize Every Word In His Post (j/k :p I know it's a forum program that does that if you capitalize the whole post :p ), but it's just something I noticed.
Original pondering: BasBas considers making the GT3 RS as his fifth or so car, but decides against it because it is property of EA.
First official try: Tool831 in his "Secret Car Pack" thread from last November.
Second try: Tool831 again, before "leaving" TDU modding to move to rFactor.
Third try: Porsche Carrera GT gives the car a try. It gets to beta stage, where it remains now.
Fourth try: TDU66 begins the project with images of the RS in ZModeller, but then stops the project because PCGT has released a small picture-update to show his return to making the RS.
Fifth try: T3hReaper, after starting a vote on it (in which the GT3 RS is a clear first-place winner), begins his car, releases first import pictures, and then makes the thread disappear for unknown reasons.
I'm not trying to make anyone angry - just show that the elusive *insert hard to find or fictional animal here, excluding the Liger* of TDU modding. Maybe someone, someday, will conquer the project. :)
