Looking at the components, the Fuji's actually a little nicer (rear derailleur)! But I get being attached. The Charge has yet to worm its way into my heart (...ew...) the way my Giant has, even though it's a heck of a lot nicer and fits me better.

I'm about 95% sure they won't sell an unassembled bike. The only way you'd be able to get it that way is 1) if they've got one of them on the floor, you could ask them to disassemble it, but you'd have to pay the cost of doing that, or 2) you buy it off the website and have it shipped to you rather than going in, buying it, and shipping it to the store.

Could you rent a bike down there?
