choices, choices ... sigh

OK, gals. Here's a chance to do some virtual shopping. Tomorrow I'm gonna go try four bikes:
Trek 7.6, Specialized Sirrus, a Fuji (don't know the model yet, but it'll be flatbar road/fitness), and Jamis Coda.
I guess I can tell what feels best after a few miles (back, shoulders, neck, position, smoothness of ride, hill effort), and I already know what looks best (I like red, but I'm trying not to pay too much attention to that). What I don't know is all the other important stuff, like components, reliability, etc. Soooo ...


IF you were old and poky like me, and
IF you were spending my money (I can afford any of these)
which would you buy, and why?
