Which limited edition?
The chances are that it is a metalic black, green, or blue, with blacked out rear lights and a 3 stripe interior.
This was sort of standard from 90 especially on 16v, but was the spec of the '88 Campaign, which was a limited edition.
I have noticed quite a few people describing a 90+ 16v as a Campaign - they are thoroughly incorrect unfortunately.
