250K is akryl easily attainable. Typical BMW stuff. Cooling usually every 100K miles.
Ac compressor will probably ho out at around 120-150k.
I’ve never had electrical problems with any of my BMW’s. Water pump is electric. If you find one with 5-6k miles oil changes it should be fairly reliable. Keep in mind though. It’s not Toyota or Honda. It needs attention from time to time and once you hear/see something it needs to be addressed as quickly as possible. If you don’t work on your car or don’t have decent shop knowledgeable with those cars you will not like it. Plenty of repairs are shown on YouTube. This Engine has magnesium block it leaks in general Bmw fashion. Valve cover gasket oil filter housing gasket and oil pan gasket are common. If left not repaired it will come and bite you. If you are tight on your budget look elsewhere.
