If that's proper vinyl sticker @ $5 bucks shipped, i'd say grab them if you still can. Last time I did the nissanexa.com stickers, they were about $10, and about double that for silver metallic.
Anyhow, splice makes some awesome stickers (he did all the jms cars for autosalon last year), so i'm going to stick with him for this run.
Heslo if you can get a hold of the font, that would be awesome.
Nozilla, i'm more inclined to go with the simple web one also. I was thinking of the big SAU logo for the rear window, but i've a feeling it might be a little too much. Might just grab a few of the web ones and just see how it looks on the car first.
