I need help!

Hi, I'm quite new here but I've been building models for quite some time. Can anyone help me? I'm currently building a 1/16 scale 1979 Pontiac Firebird Trans Am 10th Anniversary and I need help with it. I would like to know the accurate colour of the car. The overall colour is silver but the bumper and some parts of the bonnet looks like gun metal but I'm not sure. I would also like to know the colour of the interior and the engine block. Thanks...:)
