We just bought a Trek FX 7.2 for my wife, and I have a Cannondale Road Warrior (like a Quick now) that I cross shopped with the Specialized Sirrus around 6 years ago. If the basic geo of the Sirrus hasn't changed, then I think it is a little more aggressively 'roady' than the FX, though a quick check of the web site seems that the tires at least are wider than I remember.

FWIW, I bought a Trek Domane 4.5 at the same time as the FX and was able to negotiate it down ~$400 from list plus a $25 credit and 20% off on accessories, etc, etc. The FX we got for ~$50 less than list and some lame accessory package tossed in.
