Quick Summary
The BMW 3 Series delivers respectable reliability when owners keep up with maintenance, though it costs more to run than most non-luxury sedans.

Service history matters, especially on a used car. Is the BMW 3 Series reliable enough for daily driving? Yes. A well-maintained BMW 3 Series with a proper pre-purchase inspection can make a rewarding long-term vehicle.
