What is this bike model and year? Cannondale CAAD? I have an opportunity to buy this bike for $200 and was wondering what model and year the bike is? From one of the pictures I see CAAD and on another, I see seven, but I'm coming up empty handed when googling. The owner says he bought it last year. 

Thanks!

Not sure of the year; you can look up previous years and see if the color scheme is different, or if the components match what was spec'd on that year (derailleur, shifters, number of gears, etc.). 

It's a fairly entry level hybrid from a major company, so bikes like these don't go huge overhauls very often -- it doesn't look much different than the 2018 visually aside from the black crankset in the figure below.
