I think until spend $1k+ on a bike the suspension shocks on hybrids and mountain bikes just add weight and sap power. Imagine a pogo stick effect every time you rotate the pedals. You can't compare a few hundred dollar bike to a car. If you must have suspension I would get one with a mechanical lockout for smooth roads. Wider tires at lower pressure are a better way to smooth the ride out IMO.
That's a nice looking Trek but beware than step through frames like that are typically female specific frames.
