I'm encroaching on my 140k service (within the next month) and the car, although getting a little long in the tooth, still holds itself together nicely.
I've never had to replace mounts or chains, but the biggest issue I've found is ?tie rod ends getting loose. Stupid design, but start to clunk going over bumps over time. Basically an annoyance rather than a drive issue. I've only lowered the car on new springs/struts, nothing extreme. The car makes typical noises for a 10 year old (nearly) 4Cyl. I drive as a daily so have no boost issues or turbo seal issues...
3 MPS - Rolling on Pirelli PZero Neros, sitting on Bilstein B12's, stock internals... still makes me smile with the Zoom Zoom.
