mmm... i know one way you can "get it work" or better say... drive it
1. Go to your "Vehicules" folder on your game directory (example: E:\Test Drive Unlimited\Euro\Bnk\Vehicules)
2. Choose one car you like to drive cause of handling/speed/acel and that kind of things xD, I`ll make the example with de Ferrari Enzo.
3. You will have to make the backup of 4 files you can find in Vehicules folder, in this case: "Enzo.bnk" , "Enzo_I.bnk" , "Default.bnk" and "Default_I.bnk".
4. Remove the 2 Enzo files from that folder.
5. Rename both "Default" files so their names looks exactly to the Enzo files (so the "Default.bnk" and "Default_I.bnk" will be "Enzo.bnk" , "Enzo_I.bnk")
6. Run the game
7. Now when you go and search the Enzo in your garage you will find that the Enzo now looks like this default car :D
That´s not a secret car, is a default car that use the game when it don´t finds the graphics of a car.
Well... that´s all ^_^, sorry of my bad english u_u, im from Argentina :D
If you want to get you Enzo back just use your backuped files
