How's the plastic bits holding up? That's been a problem with my 2003. Switches, visor clips, barely used cupholders.
And the TC (lockup issues) - though I'm mildly chipped.
And the turbos (see above) It now has K04's.
And the valve chain adjusters
And the valve cover gaskets/seals
And the turbo oil seals (but see above)
And the CV's (normal wear item) Although I've had boots rot with the joint being fine.
Lots of other wear items but many came earlier in its 15 year life.
That said, I still love driving the car. Well, except for the Brake-Throttle Death Lag (it's a thing if you two foot it like I do).
Honestly, now that I think about it, for a 15 year old car it's holding up surprisingly well and still looks good too. However, it's got less than 100K on the clock and is garaged.
