That a bmw needs constant attention. regular oil, pressure, and brake checks are essential for a well-functioning bmw. and it will save you a lot of money on repairs due to the german engineering in bmw, most shops will charge extra fees because the repairs are time-consuming and more intricate than others.
My car is an E46 chassis BMW, that being said it is well-sought when it comes to the modified car community. in E46 bmw's the main problems you hear about are the front window regulators (my right regulator is broken) , and that various seals within the engine bay are notorious for cracking due to the high-pressure and functions of bmw. some features that i enjoy are the "sport mode" that allows me to turn from an automatic transmission into a manual for better control over the car in race-like situations. also my car has a dynamic driving feature that learns how i drive and automatically adjusts to make my rides more comfortable. i also enjoy the speed of my car, at a straight 6, im able to have a little fun on the highway and let loose on my speed while still having maximum control over my vehicle.
