It's like GT5's trading system, they send the car as a gift, you send something else back as payment (it's a trust system). Not sure if there is a limit to what can be sent per day (1 car/day for GT5 👎)
No limit I know of at least. Recently after a hard drive crash and loss of save, many friends sent me multiple cars a piece, many worth 5 mil.
The should make a forza marketplace like for GT Planet
Thats what i m talking about.
How can we not have a backup file somewhere? Its ridiculous!
Cars can be traded/gifted an unlimited amount and you can gift/receive as much as you want any time you want.
Backup saves are not allowed to prevent car duping and even if you did manage to back the save up it would be auto-corrupted/locked by the game due to the anti-cheat mechanism T10 puts in place to stop duping.
