I have a Tarmac Expert 2007. Its a beautiful ride and there are no complaints. I love it. Point and shoot, carves turns, stiff yet not as beat up on 80km rides...the low slung headtube is not for all but I like it. However you mentioned you are after a Cervelo too...thats the problem because as much as I love the Tarmac,...my SLC is simply in a different playing field altogether. My SLT is also awesome for an aluminum so with these three you can't go wrong.
