Do you want the car to keep or would borrowing one work for you instead? I have both the red and yellow nose '01 R8 race cars set to share with friends mode. I also have the '05 R8 race car too that I could set to share mode if you want that one instead. All of them are zero mile cars. So if you just want to borrow one send me a friend request. My PSN name is the same as my user name here.
If you prefer the Level 23 ticket so you could keep the car I can send you one in trade for a copy of it back (via the backed up save file trick). That's if you aren't able to work out a trade with JDCHEVYGUY.
