Problem with achieving 100% completion

[NABN00B]

Hello guys,

I've done everything I could in the game (all blue & yellow-marked missions, main and secondary sprees, unlocked all characters, got all collectibles, completed all 3 arcade games and done 100 taxi fares) but I'm still stuck at 94-95%. Has anybody ever 100%-ed the game?
Can you tell me what I'm missing?

Also do I need to unlock all 100 styles? I have about over 30 now. Can anyone tell me how to unlock some more? (without codes)

I've already written 2 e-mails to the developer, however I got no answer yet. Please help!

Have a look on gamefaqs or such. You need to unlock the final plastic surgery faces with the "coupon codes".

So there's no other way around it? If there isn't, can I find these codes in the game written anywhere?

I've just seen a screenshot showing the Player in an interior & unlocking The Romero style. I had unlocked a few others previously so there is a way to get them legitimately afterall.

can you name which categories cant be unlocked without the codes?
