A couple of weeks ago I fit a guy on a 2008 Trek Madone 5.x (can't remember which one). The design changes, namely the triangulated tubing and aero seatpost, really make it look like an Orbea. I had a tough time with the seatpost and because of the unique shape and design it would be impossible to replace it with anything else. I predict some issues with the seatpost down the line.

BTW, I have a 2005 Trek Madone 5.9SL and I've ridden it longer than any of my other road bikes. I absolutely love it. I'm also a big fan of Trek in general. They have a great warranty program and I've found most Trek dealers know their stuff.
