I recently joined the GLK owners club. Picked up a 2015 GLK250 Bluetec with 68k on it. Black exterior, Black ash trim with light seats interior (tex). Pano roof, no navigation or driving aids. So much different from the 420SEL I was driving, it was finally time for something newer, capable in winter, and not draining $85 a week in gas. Mine is 4matic (as all 250's are). The torque of the OM651 is nearly enough to cause wheel spin on all 4 wheels in the right situations. Also I drive like I stole it and have yet to see less than 28mpg, and on steady drives of 70-80mph I can get nearly 36 with the A/C on! Its no slouch either, 0-60 is delivered in torque filled quick bursts in about 7 seconds.
