Had the 100k service done at Boostworx yesterday, belts, water pump, all fluids, diff, gearbox, attessa, brakes etc. I did my own oil and oil filter so that wasn't needed. They also fixed my dodgy front/dump pipe install and reseated the O2 sensor properly (didn't quite go all the way in before due to wrong thread on JJR's pipe). Car is now running like new, purring along beautifully, gear changes are much quicker and smoother. Couldn't be happier. If anyone has been putting it off, do it, do it now, worth every cent! They also put it on the dyno, 135rwkw. Total cost incld. 3 new bulbs, $1050.
Just thought I would share.
EDIT: Forgot to add that they changed the plugs too (supplied by me)
