You definitively should have!
I noticed you have the GT-R GT Academy, is either of them 0/0?
If not, then do you want to trade for the Lv.23 ticket?
I have tickets Lv.9, 12, 17, 21, 24 and 1000, '66, '67
I also have 869 standard cars (about 100 I think are duplicates) so ask if you're looking for a particular model.
