My 98 bmw with 210k miles when I sold it was the most dead reliable car I've ever owned! Bmw i6 engines are legendary, as long as you get the ones that still have a steel cable from the throttle peddle to the throttle valve. Once u got a potentiometer with 6 wires that go to the ECU which then suggests what the electronic throttle body does, is where the reliability sort of ended LOL.
