As a regular user of Collective2, I thought it would be fitting to begin my series of reviews here. It’s difficult to start a review series in a void, so I will be comparing aspects of Collective2 (or C2, as it is often abbreviated) to some of the other sites listed in The Autotrading Universe; but don’t worry–I intend to review, eventually, as many of those sites as possible to provide further context. N.B. this review will be updated as Collective2 continues to evolve.
