Calum,
I have given Leech/Mr Mourthy lots of advice, tips, decals, fonts, font names and pics in the past (Not that it's any of your business), however I got fed up of him asking me for these things on MSN all the time, or him asking to see skins I was working on at the time then trying to copy them and then within a couple of hours see a render on here of a car that is the same colour, has some of my decals which i have kindly sent him and the same sponsors all thrown together as qucik as possibble and then being passed off as his own.
I'm more than happy to give advice to people, I have done in the past and still do.
If you really want a tedious post, have a look back in this thread and find some of your own, telling people that they have Mk. 2 Granada saloon wheels on a Mk. 2 Estate, or something along those lines.
I don't know about world class skins, but try the link in my signature below.
