you MUST have a full install of Need for Speed for the addon cars to work. ( running a minimum install, with the game running off of the CD will not detect any cars in your folder )
First, open the zip file that you downloaded.
Second, open your Need for Speed: High Stakes directory ( C or D drive )
Go to the "Data" folder, and then the "Cars" folder
Create a new 4 letter folder name inside this "Cars" folder, usually the name of the zip file, and put the CAR.VIV inside the new folder you just created. The car will show up in the game menu now.
All questions or comments can go here or in the Forum - either way, you'll get your answer.
