Considering that the batteries are warranted for 10 years and 150,000
miles in California and other states that have implemented California's
emissions-control legislation, I'd say that the batteries will last at
least that long.

Well, no.  The reason to buy a Prius today is to help reduce pollution
today and to help reduce petroleum consumption today.

Oh, oh; I guess the people who bought the first Priuses ten years ago
better start worrying.  NOT!

Support the troops:  Bring them home ASAP.

_IF_ I end up having to pay for any of those, how much more will I have
saved on gasoline by then?  I'm already down 835 gallons, and at an
average price of about $.35 per gallon over the time I've had the
Prius, that's a savings of almost $000 already.

What makes you think they will go bad?

Most conventional cars don't go to 300000, because keeping them stops
being economical quite some time before that. Glad that your Cherokee
gives you good service, but why wouldn't a Prius do that?

Like having a gear box with at least 11 cogs, and moving them in an out
all the time, pushing against synchronizing rings to adjust rotation

Standard technology is well understood and known. But KISS looks
different to me :-)

Actually turbo prop was developped after jet engines. 50 years on,
people still buy them and on short hops they seem to be very economical
and loved by the airlines.

Why would the fact it may be a transitional technology speak against
hybrids? Today it's a quite interesting package to eco conscious new car
buyers. That's what counts.

I don't know that they will, electric motors and generators potentially
have very long lives, there are electric cars almost 100 years old with
their original motors.  But we just don't know about these, they haven't
been around that long... and however reliable they are they aren't gong
to be cheap to replace.

Even assuming the motor/generators, the power split device and the drive
chains hold up to get that kind of life the engine is going to have to
be rebuilt and the batteries replaced.  I've no doubt a Prius COULD be
made to last that long, when you come right down to it any car can be
kept going for as long as you are willing to spend money on it.

I've got a total of about $,000 in repairs aside from normal
maintenance stuff in that 300,000 miles.  (Engine, clutch and radiator)

Ever look inside an automatic?  As you say stick shift technology is
well understood and I know more about the inside of those things than
I'd care to remember... my Jeep may be about as reliable as a cement
block but my 48 year old Studebaker is something else again!

I stand corrected.

It speaks against hybrids if you want to keep the thing for a long time,
if your going to buy one, drive it for a few years and sell it again
that's something else again.

Look at the battery as no more than 166 D cells, because that's in the
end what it is (they're even replaceable in packs of 6 or 8, I think).
Does the thought of these frighten you? There's 6 of them in every
ghetto blaster.

There's no drive chains, and the power split device is a bunch of gears
in constant mesh. Old technology, never breaks. The engine is just an
engine, and the traction motors are just plain old electric motors that
live a hundred years.

I would still expect the battery to keep up over 300000 - there's a
bunch of Priuses around that age really, really well. And 4000 in
repairs already buys a handful of shiny new parts for a Prius.

PSD has what... 5 cogs, in constant mesh?

So, would you buy a conventional car today, understood it's aged
technology past its prime?
