I personally view a few 'faults' as wear and tear items, certainly the DV, cam follower, that sort of thing.
There was a period a year or so ago when I had injector problems amoungst other things, and the car was getting on my t*ts a bit. But stepping back and being objective it's actually been a dependable car in the 2 and a half years I've owned it.
As enthusiasts, we really should be enthusiastic about giving these cars the best care we can (some of us are happily spending 4 figures on exhausts, turbo upgrades and BBKs at the same time). My stance is that if the car needs it, it gets it. And if we can take preventative measures against certain parts failing in the future, we should.
The problems mount up when the boring bits of extra maintenance are ignored in favour of tuning parts, or you're unlucky enough to buy a car that's been treated that way in the past - even if you intend to treat it properly, in some cases the damage might have been done.
It's not perfect. But no car is (unless you're loaded and just throw it at a dealer/specialist without a worry if and when things go wrong).
I think if I was forced to live with some of my old cars for a while I'd soon miss my GTI. It's all relative.
