Hahaha, I have no interweb for one day and come back to all this hilarity. It's so true, the little rattles and squeaks drove me up the wall! But then you'd spend the best part of 24hrs looking for it and might fix it and then, there's another one! For easy things to control, like oil, you want one that protects and feels best, cos there's plenty of other things to worry about!
I just sold my car to someone on these forums. So mate, if you're reading this, you'll sympathise soon enough . But the reason everyone (almost) keeps the skylines, is the good bits.
I think this is the way with all enthusiast cars: they piss you off every now and then, but will always make you love them again (usually that right pedal helps)...
