Alright guys, it seems that nobody here knows about the glitch that you can do in GT5 after the 1.05 update which enables you to backup
the saved game data.

I haven't tried it out yet because I don't have time and currently doing endurance race and some sleeping after it.

This glitch has gained alot of popularity especially in www.gtplanet.net in the marketplace of the forum where people are begging others to give them a free X1.

So, I have decided to do a rough guide on how to do it and share it with you guys! Hope that this post won't be deleted by any admin here because this is not a hack or something. Or maybe if you want to thank me, you can gift me a Red Bull X1 or Formula Gran Turismo (white with silver stripes). <<<<My Dream Cars

Sorry for bad english because I rushed it!

1. DUPLICATION OF CARS (gtplanet users are doing this right now and it works!)

1. Backup(copy) your data in the saved date utilities to another account or USB drive. (It is better to save the game manually in the gt5 first to prevent any lost data)
2. Start the game from your main account.
3. Give the car you want to give to your friend.
4. The car is gone from your garage now.
5. Quit the game.
6. Delete the game data from the saved data utilities in your main account.
7. Log out your main account and log in the account where you copied the game data as backup.
8. Copy the backup game data into your main account.
9. TA-DA! Now your main account and your friend both have the same car. The car has duplicated itself!

2. BUY YOUR DREAM CAR FOR FREE (NOTE: YOU MUST HAVE SUFFICIENT MONEY TO BUY THE CAR YOU WANT)
(I haven't tried this out yet but I think it will work because it is based on the same principle. I found this out on youtube but only few watched this and the video doesn't give a complete guide)

1. Create a decoy account in your ps3 to receive the car.
2. Create a psn account for your decoy account and start the game to get everything done(profile etc.) in the gt5.
3. Quit the game and log in your main account.
4. Backup(copy) your data in the saved data utilities to the other account(not decoy account) or USB drive. (It is better to save the game manualy in the gt5 to prevent any lost data)
5. Start the game from your main account.
6. Buy the car that you dream for.
7. Get the car from the car delivery.
8. Now you have the car in the premium/standard section in the garage.
9. Send the car to your decoy account.
10. Quit the game.
11. Delete the game data from the saved data utilities in your main account.
12. Log out your main account and log in the account where you copied the game data as backup.(In case you backup in the other account but not the usb)
13. Copy the backup game data into your main account.
14. Now logout from the account and login to the decoy account.
15. Start the game from the decoy account.
16. Get the gift from the community section and goto the car delivery section to get the car.
17.Send the car back to the main account from the garage.
18.Login your main account and start the game. TA-DA! You have the same amount of money before you buy the car and you received the dream car from your decoy account!

NOTE: ONLY ONE CAR A DAY!

Feel free to comment about this and please help me to check that whether my guide is complete or not.
And if somebody tried the 2nd glitch and its a success, please tell me here. Thanks!

Oh yeah, if somebody got a X1, please dupe it for me! THANKS!
