I was pondering why you were talking about insomnia for a second, then I realised that it was 1:24am and I'm still mucking around on a computer, and also, you know, you're in Finland.
My thought process on the GR. For the price, if I need to rebuild the engine, I'll just get the MK2 components popped in. Price to improvement ratio looks not great, especially with finance cost being much higher. I'm not taken with the looks, and actually... I've gone off the back end as well now. The only bit visually I like is actually the real diffuser, and the badge delete and reorganisation. I don't like the third brake light reposition, I don't like the full width rear light bar thing, and I don't like the fog and reverse light in the higher position... as they are visible at certain angles despite efforts to hide them. That whole lighting area looks very busy, and a bit of a cluttered mess. Also wtf is the point of a third brake light that's not at the elevated position?
