As a Madone owner, I'll comment. I had a problem at 85 miles with my Madone. I thought the LBS would go to Trek and sort it out. Nope. My LBS, at their expense, replaced my bike for the exact same one (they did swap out wheels and tires since they were dirty). I do not know what Trek would have done whith what may have just been a major paint issue on the seat tube or maybe a structural one. The point here is another factor in the bike purchase equation is find a LBS you like and trust, as well as a bike that fits well and makes you smile.
