The change in derivability of our syncro Westfalia after the
installation of a new Oxygen Sensor is so remarkable that its like
buying a new car.

I had no idea that the old OS was bad. I just reasoned that if in the
USA the Vanagon has a mileage counter devoted exclusively to warnings
about changing the OS, then maybe there may be some merit in changing
the thing.

I had no idea that the engine was doing anything other than it should be
doing. It started; it went up and down hills; it rolled along freeways;
and it gave good gas mileage (20+ mpg)

But now I know that our syncro Westfalia is really one heck of a nice
machine. It doesn't just go up hills, it climbs hills. It doesn't just
roll along freeways; it purrs. If this is a dream, let me sleep.
