The good thing about the creed is the year isn't really all that relevant. All they've realy done since the new V2's came out is improve them. All the new parts are compatible with any V2 gun so you'll always be in good shape.
Things to look for if you're buying it:
LP metal poppet/valve
Upgraded front LPR shell
There are other upgrades but those two are the most important in my opinion. If you have those, the gun will work great.
Creed Battery f/s
Creed Replacement eyes f/s
Creed replacement solenoid f/s
06 alien remains board f/s
