10v.... interference engine?

[MXHOWES at aol.com]

In going back thru the archives I was convinced that my 10v ('85 4kq & '88
80q) were non interference engines ... ie. you break the timing belt and
nothing else is broken.  The 20 valve is a different ($) story.
Now I see in the  Marketplace some guy is selling his '90 200tq 10v with a
broken top end because of a timing belt slip. Either:
                           a. He has a 20v and doesn't know it.
                                                             b. Something
else caused the damage
                                                             c. He doesn't
know what he is talking about or
                                                             d.  I don't know
what I am talking about

Which is it?
