Awesome quality, I'd just put in another vote for a 'barcode' version of the Martini logo. Gran Turismo might do it to get around alcohol advertising laws, but it's a great (and familiar) compromise for the mirrored textures too.
Great work as with all of your car skins. I have a bit of request if it is not too much trouble...is it possible to make those 3 skins with Martini logos on them to have barcode instead of Martini vritten? So that we can have it not mirrored, while having those logos on the car.
