they're generally pretty reliable, provided that you're not going for a 335. the n/a straight 6 has proved time and again to be a very reliable and smooth engine. in terms of electrical problems, i actually haven't heard of anything. a burnt out brake light here and there is about it. theres nothing on the car that's deathly expensive to replace or repair, and if you get a CPO you'll hold on to another 2 years of warranty - which will cover parts and labor on most of the drivetrain and engine repairs.
be wary if you're looking for a 335 though. they're known to have problems with the high pressure fuel pump, which i've experienced myself on several occasions. during my 3 years with the car, i had to replace 3 fuel pumps, the camshaft, one turbo, the wastegate actuators, and repair a faulty link between the diff and driveshaft. needless to say it was a real pain in the ass having the car constantly running like shit, and BMW refusing to acknowledge any problems until the car literally died on me in the middle of an intersection.
