I just returned from a 4 year assignment in Wiesbaden, Germany. I bought my 2017 MKZ Black Label specifically to take over there with me, it was my third assignment to Germany and I knew what I wanted. The AWD 3.0 did not disappoint! I put Vredestein all seasons on that were rated for 168 MPH and moved my oil changes to twice a year. I never had a single issue with the car.
The 155ish cut off was annoying, accelerating up to it gave indication of quite a bit more left untapped. But, I did not want to mess with it too much while still under warrantee. Getting up to 155 was amazing, I hurt a bunch of feelings of the BMW and Mercedes crowd. Unless it was Italian, AMG, or a true M - I normally got in front of it - for a bit. The 911's almost always smoked me, as did any turbo Porsche. But they were intrigued by the MKZ and I got lots of looks. Best money I every spent.
