Just move Folder called MULT (when you unpack zip file) in your NFS 3
directory in:
...GameData\CarModel

In MULT folder you should have 2 files (car.FEC and car.viv) to work corectly.

Note: You cannot have more than 50 cars in CarModel folder. All cars must have
a 4 (four) letters in a name of a folder. Car is tested on english
version of NFS3, so if you have any problems with car on other version of NFS3 please
contact me.

That is all.
