At least individual examples do exist. I've owned mine for 20 years, in that time I have had exactly 1 failure to start (first start after the winter layup, fouled plugs), and no inflight failures at all. Other than scheduled maintenance per the manual, the list of repairs in 20 years has been:

* replaced exhaust muffler per A/D
* replaced water pump due to progressively worsening seal
* preemptively replaced belt idler bearings which were judged to be noisy
* replaced coil #1, internally intermittent

I've rarely owned a car that had fewer repairs. I'm not going to argue that this glider is as reliable as a modern car, but with vigilant maintenance, reliability has not been bad relatively speaking. Perhaps I have been lucky, but I know other owners who are equally lucky. I own two boats, each of which has required more unscheduled maintenance than has the glider. Boats and gliders are both made in prototype quantities, an expectation of reliability equal to an automobile (made in millions) is naive. But of course, even in an automobile, good factory support is desirable.
