Rather than start a whole new thread for one quirky question, I just thought I'd post this on here. Can anyone tell me why it was common practice for Trans-Am teams to paint the interior, trunk, and engine bay a separate color from the body? The most popular color was light grey, but there were other variations too. This is something that wasn't really practiced outside the US. In most other countries, the interior, engine bay, and trunk were all painted the same colour as the outer body, because it was easier and quicker. There is a lot of work involved in masking off those areas to paint a different color.
