I have owned and driven 6 MB diesels over the decades and my kids still drive 2 of them. Yes safe and solid.
My new ride is a 2015 ML 250 bluetec with the 4 banger diesel engine.
I have put 45K miles on since new and I have to say it's the best MB diesel I have ever owned. It drives like a dream and has power to spare at low revs.
I think it's a combo of the 7 speed tranny and the twin turbo engine. A touch of my foot on the pedal and it kicks down a gear and kicks ass up to 4000 rpms.


I have a 5 mile up hill highway stretch on my way home where I regularly hit 100 mph when no ones around and I think the engine is under 3000 rpms.
I am a safe driver too.
