Is there anyway to get my old save? (if not can someone donate money and cars?)

Pretty much lost my save because my brother thought it was a great idea to format my usb with all my save data a few months ago, and i wanted to know if there is any way of getting my stuff back?
If i cant, is anyone willing to donate?
(if you think im lying, look at my storefront and achievements)
