As a car enthusiast, I have to disagree with your car analogy. Most carmakers deserve their reputation. While some Land Rovers were even more unreliable when they used BMW engines, and certain models were more reliable because they had more Ford parts, in general, all Land Rovers are unreliable.

Has BMW ever been reliable? Yes in the 90s and before, since then? No. They just don't care, they're sold as lease vehicles to people who care about having the newest stuff for 3 years and then move on.
