Hi guys a new member on here, I have a 2017 E350d V6, and am an active member on the Mercedes forum (sorry🙁), but have just persuaded my elderly retired parents to purchase NX300h Luxury 2018, but there are plenty of owners on the Mercedes forum with owners having issue with Nox Sensors, and adblue and dpf, so what spacewagon52 says is correct, so factoring that, and also the noise of a diesel car, (unless it’s a V6 of course), then if the mpg of a hybrid and a diesel is more a less the same, then hybrid would be a better choice. Also in London a residents permit for a diesel car also has a added supplement, and diesel also being more expensive the petrol. Low mileage drivers should probably not get a diesel, due to the dpf and adblue issue, my retired father does around 3k miles a year, this was the reason I told him to go for the NX, rather then anything else.
