Well... It would be going well if I could find the rest of the decals.
And a nice big image of the flag.
I managed to find the 'Maguiars' logo, but that will take a while to recolour.
I just need the 'WantMyRide.com', 'Andersons', 'NUTS', 'Transcar' and a few others which I can't make out decals.
If you can find the font used in that watermark you could recreate the logo. I think it says effective vehicle branding underneath, and www. and .co.uk at the sides.
