Still use my 2004 (I think it is) Madone SL as my ‘nice’ road bike, that’s knocking 8 years old. Whilst I don’t doubt that modern road bikes are far superior I still love riding it, it’s incomparable to the 2010 Allez I commute on, comfy, light, stiff. It’s been ridden through winter for many of the years I’ve owned it. It probably gets cleaned every 6 months, but it’s a great bike! Quite like it to break so I can get a new Madone on warranty.
I’d go carbon all the way. Trek recycle carbon, so ooOOoo’s comment is negated.
If you’re a clumsy oaf and these are likely:
take a tumble/get the boot slammed on it/slide down the corner of the wall at the cafe
Then you should probably avoid cycling altogether, in fact, you should probably avoid going outside unsupervised.
