To help you out Jay..

Should really be 1500 quid upwards or there abouts- from the pics looks like its on Mi16 management (no dizzy- just the cap) a let down is its a 1.6. All the running gear is inferior to the 1.9 stuff - so expect to get asked if its got 1.9 stuff on it as a lot of people change it over.
(basically none of the bigger brakes etc bolt straight on- drive shafts are smaller and suspension arms and stuff- from what I am led to believe)

I'm fucked if I know how to tell the diff.

As you dont know much about it box/brakes etc its gonna be a pain as those are the questiosn people will ask- but for what little you know I am sure you aint gonna see less than 1500 quid- that seems to be going rate for somet like that on fleabay
