All we have here is opinion when it comes to personal preference on colours/wheels/options. I loved TR on a GTD, slightly less so on a GTI, and not at all on an R. Front end on, the R looks a lot like an SE or a GT, so (IMO) needs a colour you don't see so often on a low-mid end Golf (which puts the silvers/greys and TR out of contention for me) if you want it to stand out a little (some won't want to stand out at all).
Really keeping an eye out for minor potholes, more so than I ever did in the GTD - I could put it down to babying the car because it is new, but you do feels the sags in the road a bit more on 19s.
