I did my cousin's car a c55 amg with the fake CF overlay. It actually turned out great. If you have 2-3 people helping lining it up and pulling and a heat gun it makes thing way easier. We ended u applying in the cold so it was tougher so had to hit it with the heat gun often. The overlay on our cars will be really easy actually since the roof area is so small. I say go for it and DIY!
