I just got on my xbox for the first time in a month and i was gonna mess around on Forza but i had to go through the opening scene and first race but when i went to my garage ALL my cars were gone. Ive lost everything but i still have all my acheivments. Whats the deal?
All cars are saved to your hard drive and not t10 server. Are you still using the same hard drive as you used months ago?
i have lost everything aswell… and i like to just play a bit before dinner with my son, so i will never ever be able to get all the great cars i had, to play with 
maybe ill post a cry for help, maybe someone has something they want to donate… i know i had, and did with before… its worth a try
That would be a bummer. I always wonder about this too. LOL.
