Okay, I'm looking at buying my first Golf, and the model I have wanted for a while now is the iconic Mk2 GTI 16v.

I have been looking for quite some time, and I saw this post on Gumtree:

VW GOLF 16v GTi Genuine rare fast car volkswagen | Cars | Gumtree Australia Botany Bay Area - Botany

Now it looks like a bit of a bargain from market prices that I have seen, however when I looked closely I wasn't totally convinced that it was a true GTI, but a standard golf mk2 converted to the 16v through an engine swap. This is mostly because the GTI badges are missing, and there isn't the red badges that I have seen on the doors of other 16vs. Fuelling my suspicions, there are no interior photos. Also, i was under the impression that the GTI's didnt come with the option of a sunroof, although I could be wrong on that point. When I prompted the owner for more information, he replied that it was an 86' model, although I was under the impression that Mk2s were 87-93?

Your opinions are appreciated, I would absolutely love it if you could prove me wrong here.
