[V8] How many miles is too many miles?

[Roger M. Woodbury]

Despite my complaining a week ago about the scarceness of V8s for sale, I
see that this is another one for sale in Hotlanta.  This one is a '93 and is
the coveted (by me) black on black.  VERY high miles...almost 200,000, but
the pictures make it look very nice indeed.

Soooo. Question of theory.  How many miles are simply too many miles?

Now the particular car that I am speaking of has been for sale by the same
owner/dealer before.  In fact, if memory serves, the car has been available
for about two years as of now, and I suspect more than that.  I can't
remember if I ran a Carfax on this V8 before, but if memory serves, it has
had only two owners in the 190,000 miles of its life.

Still and all it looks quite nice.  So, here's the deal.  Suppose that some
Audi Fan bought this one with the idea that the fool boat of maintenance
issues and schedules were going to have to be completed if not immediately,
over time:  in the humble, or not so humble opinion of those on this list,
how many miles would be too many miles to start with?
