GLK350 help please!
I'm looking into buying a 2010 GLK350 with 190K miles on it. A previous mechanic said that it wouldn't pass emissions without replacing the engine? It runs fine. What in the world would cause the engine not to pass emissions if it's running ok? What other "gremlins" should I be looking for on this particular vehicle? Thanks for any insight!

The 2008-2010 GLK350 had a M272 engine, and a certain range of those engines had a balance shaft issue. When the balance shaft problem happened, it was very expensive to fix, and in some cases it was cheaper to replace the engine. It is possible that the mechanic made an assumption that you engine is part of those problem engines, and just told you that to discourage you from buying it.
There are ways to check. If you have a code reader, you can check for codes P1200 and P1208. If those codes are there, then the engine has the balance shaft issue, if on the other hand, the codes are 0059, 0060, 0063, 0064, 0271, 0272, 0275, and 0276, then the issue is the camshaft solenoids. those can be done for a few hundred dollars, or even less if you're a DIYer.
Another thing you can do, is to check you VIN number against a VIN decoder and look at your engine serial number if the number is lower than 2729..30 468993, then it might be one of the problem engines. If it's above, then it should be OK. Also, just because your engine falls in that range, it doesn't mean it automatically will fail, only about 15% of those engines will develop the problem. The only way to know for sure, is to check it with a ODB code reader.

Oh, I don't know about walking away from a "free" car.
But @formerjeepguy is right. Unless the car is really well priced, in otherwise great mechanical condition, and you're either a DIY person or have a great mechanic, it'd look elsewhere. I would suggest you look for a facelift model, 2013 or newer. Those had a newer engine, more horsepower, updated fascia and interior.

2013 glk 350
What’s the price. Was it highway miles or city driving? Do you have maintenance records ? At 190000 m. You could get 10-15000 in failures the first year if your unlucky . What reason did he say it would fail, I’d guess the rings are worn and it burns oil. Only if it was super cheap , had records and was fully checked out would I consider it, but just regular overdue maintenance could be 3-4000 done by a cheaper independent and 4-10000 done by mb. It could be an expensive experiment .

Get a scan tool and know for sure.
Might need new intake manifold, O2 sensors, crank venting/PCV, EGR, coils, plugs or just fresh gas.
M272 engines are actually pretty reliable and easy to work on and GLK itself is super easy to work on and to maintain. But if you are not DIY type, the ongoing expenses will make it prohibitively expensive.
The going assumption should be that by now most of the items should be replaced, if they haven't been.
