This is one of my greatest cars
This folder contains:
- 2 simulation files (.sim)
- 3 files necessary for the texture (the main one is the texture of the car which ends in .crp)
- 1 savegame generator
- 1 NFS 5 PU File editor 

Extract the 2 simulation files into:
C:\Program Files\Electronic Arts\Need For Speed - Porsche Unleashed\GameData\Simulation\CarData

Extract the 3 texture files into:
C:\Program Files\Electronic Arts\Need For Speed - Porsche Unleashed\GameData\CarModel

Then follow the instructions to install the savegame generator.
Once you have done that, open the File editor and find your savegame file (.sav) in:
C:\Program Files\Electronic Arts\Need For Speed - Porsche Unleashed\SaveData

Click Open and then you can edit your money, your factory driver missions and install new cars
Type the name of the car and type the name of the texture in the .crp box, 
type the name of the simulation file in the .sim box.
Close and save, now run NFS 5 PU

WARNING: type the correct name, with the correct spelling otherwise you will get the default settings of the car!

Enjoy your NFS 5 PU,

ProTuner
