Sales of BMW's 6-Series and Nissan's GT-R shot through the roof in October. This occurred during the same period in which BMW Z4 sales plunged and Nissan 370Z sales dove for the basement. The 6-Series came within 28 sales of beating the Porsche 911.
Speaking of the generally unbeatable Porsche, 911 sales fell 17% in October. The next-gen 911 will soon be upon us. Many customers would therefore be reluctant to acquire the now out-dated 997-gen 911.
A 17% drop would certainly have been an easier pill for Mercedes-Benz to swallow with its SLS AMG. Sales of the Mercedes-Benz's exotic-looking supercar fell 78% instead. Through ten months, the SLS AMG is up 13%, though sales of the lower-rung SL-Class are off 38%. All these numbers and more can be viewed in the table at the end of this post.
