That is ridiculous. Like buying a roast chicken carcass after someone's eaten the meat.
Let's assume this is actually a Cervelo, which I wouldn't count on. If you want to ride a Cervelo, you must want the bike to also have components worthy of a Cervelo. So you buy this frame, throw away the crap parts that the bike stripper slapped on, and go buy the appropriate components. You will sink $1000 or more into the project plus loads of time/effort.
