I have literally put my Mk4 up for sale last week mate, 3dr dark met.Blue turbo gti on a T plate. Lovely condition etc etc....

Pretty much all of them are 150brake, the 180s are rare as hens teeth, as you said all of what you said above are extras, they basically came with fook all!!!! The earlier ones had recaro interior (embroidered logo) and the later ones had seats made by VW (but look the same). Cambelts at 70k I think as well as tensioners.

if your interested in mine mate let me know and ill take some pics! My friend has just finished cleaning and polishing her so looks spangly! I've also got 18" alloys on there, recently had the cambelt service done, replaced the rear axle bushes as well which are almost guaranteed to fail at some point and are a bitch to do! (I had Powerflex ones fitted to mine!)

Cheers
Chris
