I tend to agree. I, personally, wouldn't buy a used carbon bike unless I personally knew the seller well. And, frankly, at that price, it makes me wonder if the bike was stolen.

To the OP, I understand your desire to upgrade to a new bike after only a few months, but you can get a good, well fitting bike for less than the price of a new or used Orbea (although Orbeas, are indeed, lovely). Based on the measurements you gave, I have to wonder if your Felt is a little big for you. As Tulip suggests, start test riding locally. Hopefully, you find something you like.
