IMO, it's in that in-between era where it's not really "classic/vintage", and it's not up to date with modern design. I expect that the bike rides very nicely, and performs every bit as well as it always has. Being that this thread is a beauty contest, "middle aged showgirl" is probably an apt analogy. Updating parts won't change the exposed cable routing and era-trend graphics, but would help get the most out of what you're working with. Personally, I think the white saddle and bar tape work well on that bike. If it were mine, I would trim the steerer so the top cap sits flush on the stem (if you're still trying to dial in your fit, don't do this).
