Is that a serious question? I own 3 different 5-cylinder Mercedes diesels right now, (OM617 engine), so I'm definitely not a hater, but it's an absolutely prehistoric, agricultural motor compared to anything newer. Even compared to the mid-'80s OM 603 6-cyl. MB diesels. And the newer ones are light-years ahead of those. The OM617 is not even a cross-flow head design, the intake and exhaust manifolds are on the same side. It is indirect injection and not efficient/powerful/smooth at all compared to newer diesels.
And the newer ones will last just as long with the same level of maintenance. It's a huge myth and fallacy that the OM617 just goes forever w/o proper maintenance. I've seen many grenade with less than 150k on them, (sometimes less than 100k), from lack of lubrication or a bad injector. Yes, they are a lump of low-output iron and they will last forever
with proper maintenance. But no one would stand for their performance in today's cars or trucks. The modern diesels are fantastic.
