I liken buying a watch to buying a suit.
I want a nice one, I want it to look good and I want it to be different to most other peoples.
Buuuuuut, as with both, once you get over about £300 or £400 or so then I don't see the point or the value. I wear a suit about 4 days a month nowadays and I only wear a watch when I wear a suit or go out with the Mrs to a restaurant etc.
Therefore I have a Hugo Boss watch that was about £450 and a diesel watch I wear to the pub etc.......
If it hasn't seen a dealer in nearly three years, you might want to check consuambales such as pads, disks, clutch wear, clicky axles, synchro mesh etc etc..
Price is decent for the age/mileage, but as you know, it's not a GT so expect to struggle when you come to sell unless you price it cheeeeap.
Keys are pretty expensive, circa £200 IIRC.........
I'd ask the dealer to put it through a P3 at a dealer before purchase..........
