Should I pay $1300? 2017 Trek Domane carbon w Ultegra Di2

Shopping for my first nice road bike after putting in a lot of miles on my hybrid and old borrowed road bikes.

This 2017 Trek Domane full carbon with Ultegra Di2 is listed near me for $1300; includes carbon wheels (unsure which) and 2 Di2 batteries.

It seems from searching like the BB90 on Treks from this era might be a concern and also this is a lot of $$ for rim brakes.

Bigger picture, I'm willing to put in work to learn but I'm currently very much a rookie at maintenance – does that make it a bad idea to pick up this bike that's a lot of bike and somewhat older? Otoh don't want to miss out on a steal and riding something faster and nicer than I'll be able to afford new for a long time
