Best of the breed
 Owned a 328D X Drive and thought that was the best ever till I replaced it with the 535D M Sport. The 5 has tons of torque and hp to get this large heavy machine up and going. Extremely fast and smooth. I recommend the M Sport suspension as it keeps the car light on its feet. The steering is anything but numb. We've taken several long trips and couldn't be more impressed. Got into the upper 40's MPG at highway speeds with a fuel range around 700 miles. Arriving rested every time. Mine is loaded with options including heated ventilated seats that couldn't be more comfortable. They are the premium option seat and are the most comfortable I've ever sat in. It's loaded with safety features including accident mitigation which was put to use a couple of times. The heads up display is clear and integrates well with the GPS mapping feature. Haven't had one issue with the car in 15,000 miles. Even the tires are holding up. I expect I'll get 25,000 miles on them. They are the staggered Michelin Primacy run flats.  A good tire choice for this car. It is mostly a garage queen along with its big brother a 2017 X5 35D XDrive. As you can see I'm hooked on diesel after starting with that great 328 D. I'm trying to find a fault with this car but I just can't. Check back later and I'll do an update.
