the problem i find with usin g other save games is the cd keys need to match and to easies way to do that is to download the regediter for nfsc and then when you open it it automaticly goes to where all your saved games are and you just need to make sure the 2 numbers match and you delete the 1st # then copy and paste the nuber in the 2nd box cause that is your cd key and put in in the 1st box and click save and start the game and load your saved game.So If you know a friend that has the game completed 100% or you can find a file online somewhere you just edit it with this program and save it saves in your /Documents/NFS Carbon folder that was created when you installed the game so no need to know where the file is or where to put it it does it for you enjoy......

P.S here is where you can find the reg editor for your save games or some1 elses
