don't want stock in local shops to be my limiting factor. For example, I learned springing for carbon might not be a horrible idea after all, and I'll definitely bother going out of my way to a Felt dealership. Something I wouldn't have done last week
Thank you everyone for the feedback.

It doesn't have to be. If you like the ride on a certain frame, but the bike you test ride only has Sora, then ask the LBS if they can order it in Tiagra/105/Ultegra. If it's an older model that they really want to sell, maybe they'll put a new groupset on for only a minor cost.
When I got my Fuji Sportif from PB, I road tested a bike that only had Claris on it. But the frame fit me as well or better than all the other bikes that I had tried (there and at other LBSs), so I ordered a Fuji Sportif with Tiagra. I've had no major complaints about the bike.
