Just make sure you like the fit that the Emonda is made to give a rider. And that is a fairly aggressive fit. For a 58cm frame you should probably be at least 180cm or better.
The saddle height on that one looks low in the picture. Or perhaps the owner has the stem flipped to put the bars higher. So they apparently bought the wrong model bike for their preferences. A Domane would have given them a better fit since from the bikes setup, it's seems they didn't want a aggressive fit.
Can't say anything for the price. But realize that with the rim brakes your options might be a tad more limited if you ever want to put better wheels on it.
