Mine passed 180,000 today. It still drives better than many new cars imo.
Got a chance to test the new GM pads I fitted all round a few days ago. I can see why TB and others recommend them so strongly. They were superb. 
Are these the genuine ones as per factory fit as opposed to the TC ones? I have had a few sets of those and the pedal feel is much improved over the TC versions.
The TC ones are very wooden on the first application if the car has been sat unused for several days. The OE ones do not suffer this

I tended to use OE on TBE (in a misplaced effort to reduce brake dust - failed!

) and TC on the Bullet. Apart from issue above, I'm not sure there is a noticeable difference, maybe the OE have a little more feel at slow speeds. Personally, not worth the extra £40 for me, esp considering the way I get through brakes.
(That said, I've probably got enough OE sets to see TBE through)
