Tutorial to fix problem with 2.10 update.
Your problem all starts with undeletable car/s which is in your garage/save game.
The last place you could use that save was in version 2.09 of GT5?
You need to revert back to 2.09 and do a few simple things so you can get your save to work while in version 1.00.
1. Don't delete anything, That includes any DLC. Nothing needs to be deleted.
2. Downgrade to 2.09 How to downgrade? Go to
GAME DATA UTILITY select GT5 / triangle / delete.
You now need to install updates to get you back to version 2.09. You could do this manually from the internet or use a version of the GT5 disc or Academy discs which has updates already on the disc?
3. You need to find for your ghost car/s, (Undeletable cars.) The cars are unable to be choosen, sold or deleted. When you find it or them go to next step.
4. Go to your GT world menu And click over the options / Design options / and change background color to the first one (BLUE) and Backgroud image to the first aswell (Afternoon one)
This step is still under construction has some things could be tried slightly differently.

But the main thing is that your save in 2.09 needs to be able to open in version 1.00 so things need to be altered to do so.
5. Again go to GAME DATA UTILITY and delete the game to go back to 1.00 version. (If version 1.00 does NOT work for you. You could try the first update which is 608mb and that takes you to version 1.05.) You need to use the First GT5 disc edition?
(No other versions of the disc will get you back to version 1.00)
6. Enter the GT5, Say no to updates and go to your garage. Delete the car/s
7. Once you have done the above steps You can then install back to 2.10.

After completion of the updates and you have a working save that loads in 2.10
You may have to go through the process of updating any DLC you may have. Or any that will have the exclamation marks on them while in garage view.
You can go to your account manager on your XMB and redownload them or re-install them?
Plus you can aslo check by going to PSN store and they will be in your download history. So these items are not lost but just need to be reinstalled. Plus there are many threads on the subject on how to go about this so help is there for anyone who has problems?
Plus its advisable to install the family upgrade pack so all DLC is available in all accounts.

While you are now back in version 2.10 you may have a garage full of cars but the thumbnails look a bit crazy.
Just click on the trianlge in garage view and create thumbnails for all, This will take time depending on how many cars you have.
