 Go to the "NEED FOR SPEED HOT PURSUIT 2" folder
 Then in to the "Cars" folder open the file named Cars.ini
 [Save it as another file (Cars default or something)]
 Then you can see some thing like this, (but not only a one)
 
     [car12]
     name=f50
     mfrname=kTxtFERRARI
     displayname=kTxtF50
     class=1
     traffic=false
  ** price=80000 **
  ** nfsprice=160000 **
     stat0to60ID=kTxtF50_0to60
     statTSID=kTxtF50_TS
     statTSKPHID=kTxtF50_TSKPH
     statHPID=kTxtF50_BHP
 
 Change the "price" and "nfsprice" as you want. Then you will be 
 able to by FERRARI F50, as you gave it. 
 [do it to all the 23 cars If you like]

 Start You're The Cop mode in single player under the beginner difficulty setting.

 Faster cars: 
 Note: This procedure involves editing a game file; create a backup copy of the 
 file before proceeding. Use a text editor to edit the "cars.ini" file in the 
 "cars" sub-folder in the game directory. Change the "mass=" value to "100" 
 for a faster car. 
 
 Open the folder of a powerful car, such as the F1, F50, etc. Copy the "car.ini" 
 file from here and paste it over the original "car.ini" file of a slower car in
 its own folder (for example, the Elise). This instantly gives that car the speed 
 and handling characteristics of the better vehicle. Note: Back up the original 
 "car.ini" file of the slower car in the event that you want to revert it back 
 to its standard settings. 
 
 Cheap Cars & Tracks:
 Open the cars.ini file in the Game's CARS folder using notepad and change these lines
 
 price=10
 nfsprice=10 
 
 For cheap tracks open tracks.ini in the TRACKS folder and change all lines starting 
 with m_price to look similar to this
 
 m_price[0]=10
 
 Free money:
 To gain extra money you must first have not bought too many tracks. End the game 
 if it is not already closed. Go to the location of your file. Usually it is stored 
 under C:program filesEAGamesHot Pursuit 2. Next go into the file called tracks. 
 In this folder you should find a text file called tracks, open it. If you scroll 
 down you will notice that all of the tracks are grouped in an organized order. 
 you should notice three or four numbers with some of them being different and 
 some of them the same. All of these numbers should be in the thousands. Change 
 all of these numbers to a negative number such as -60000. You may wish to change 
 all the numbers for each track to a negative number. Exit the program clicking 
 YES to save. Start the game and buy a couple of tracks, when you buy them the 
 computer will end up paying you money. You will know if you have done the program 
 correctly if the computer says the track costs -60000. Also you can switch the 
 track to backward!
 
 Gametip:
 It worked fine with these mod's.  change car price to price=0, nfsprice=0.  
 change track price to m_price= just put a - in front of exesting price.  
 Then start game using desktop shortcut and you will find all cars and tracks
