These engineers did a very poor job. If they had worked a little harder, they could have made the car so that you had to pull the exhaust to replace the brakes and the spark plugs. I sure hope none of them lost their job for making it too easy to work on.

I like the "cut the bolt" idea. That's how a German would do it. Easier than removing exhaust.
