Ok, the 04/05 and 06/07 have a different graphic, different tail profile, and the 06/07 is larger in the tips and tails A.K.A more sidecut. Most importantly which noone has mentioned yet: all models before the 05/06 have wooden sidewalls which look mad pimp but are prone to cracking (my 04/05 190s have a cracked sidewall =(...should be ok though.)
