After a slightly extended Christmas break we're back ladies and gentlemen, and hopefully your Christmas was as fantastic as ours were. To each and of you that sent us a holiday greeting, thank you, sincerely, from the bottom of our hearts. We are truly appreciative for the many kind words, and as we enter a new year, we wish all of you much joy and happiness in whatever journeys you embark on. As you can imagine, our time away has left us a little behind schedule, but we'll do our best to get you caught up on that which we missed, starting with a batch of new Mercedes reviews that analyze a total of three models: the S550, the GLK350 4MATIC and the C-Class range. Like each and every one of our other Review Roundup installments, you can find excerpts of what reviewer's thought of the trio as well as links back to the full articles immediately below.
