Nismo Fairlady Z Z Tune (not S Tune) would be nice.
Also, do you want the ticket or, to glitch the cars?
Ticket >
-Get ticket, save data, and then back up your data on USB and/or another PS3 profile
-Load data, use ticket
-If you get the desired car, save data
-If you don't get the car, exit, delete your save data, and then copy your back up data into your main account
-Repeat step 1
Glitch >
-See the glitching thread for more information
-Make sure your save data is below 4000 KB
-Borrow the desired car
-Delete your GAME data, not SAVE data
-Load game and do not update
-Change to a different car
-Update the game
As you want all three Pescarolo's, you'll need to do some ticket duping when you get the L23 ticket. Or if you glitch, you'll need to do it three times.
If you don't want to mess with your main save account, create a second PS3 account and start a new game of GT5 on that account. I can send the ticket to that account, or you can use the just use the borrow glitch with the cars on that account, set them to borrow when you're done glitching, and then borrow them on your main account while you wait for level 23 tickets, or for the cars to show up in the UCD or OCD.
