BMW started as a founded in 1916 as an aircraft engine manufacturer then they transitioned to motorcyles (R32, 1923) and cars in 1928.
BMWs are reliable and great responsive engine they also have great handiling they have models like the series 3 are practical for daily drivers but also ofer sporty performance.
Bad stuff about them is that they need an expensive specialized oil and very likely for the engine to fail in oil leaks, parts are really expensive and ofter require specialized labor.
