You just have to accept that any car is not going to remain perfect.
Whilst having a stone chip, dink or a dent knocks the sugar off your pudding, that's life.
Either you curse and swear, maybe repair or well, there isn't really an "or".
I'm not saying its not annoying, but once you have one or two minor blemishes, you get less cross as the others inevitably mount up. I was spitting fur a few weeks after I got my GTD and realised that the white thing on my bonnet wasn't bird poo but a large stone chip... but its still there, along with half a dozen others now.
I guess you could buy a 35k car and get one of those garage storage bubble things, leave it in that and never take it out unless you are polishing it, but really, just buy one of those ornaments and keep it on your mantelpiece - its far cheaper than a car. I'd probably choose something more exotic than a Golf though if I wanted a collectors piece.
Your car isn't an investment piece (well, not unless maybe you can keep it for 100 years), a car is just a depreciating money pit.
