Does Toyota have two series of seals, the ones they put
on a $20k Toyota that leak, and then some they spend an extra 50 cents
on they put in a Lexus that doesn't, for which they charge an extra
$15k? I'd love to sit in on a session with THOSE beancounters!
Sounds funny but who knows.
I would not be surprised at all if they had different type seals
for their upscale models. The overall reliability of a car doesn't
come from just superior engineering of a few main components
but from enhanced reliability of each tiny little part. Say you
have ten parts, each with 10% probability of failure, this results
in a product that is certain to break. For a reliable car with
hundreds of subcomponents even slight improvement in all
pieces can add significantly to overall results.
But back to perspective on maintenance: my Subie needed seals about
every 60k (didn't always get 'em), and about $25 covered the cost (I do
my own wrenching.) It blew up at 360k miles (not a seal issue, BTW), so
seal cost would have maxed at around $150. So, averaging about 30k mi/yr
on that car, once every two years I had to toss in an extra $25 in parts
and maybe an extra hour in labor when doing the t-belts (I work
slowly!), and the reward was a car that went over a third of a million
hard miles (including lots of dirt roads and other less than perfect
stuff that probably reduced its life by a third to a half.) It all seems
pretty cheap to me in the grand scheme of things.
It is. Most of the time it makes more sense to keep
an older car then to buy a new one, especially if the thing
has a good track record. A new car has a sort of very
costly reliability insurance premium attached to it. A lot
of people who would admire you for your accomplishment
(360k) would also be scared as hell to rely on such an old. or
high milage vehicle. They would get rid of a perfect car once
it got to 120k or so. I guess the risk aversion with respect to
reliable transportation is just very very high, at least for the
working class whose jobs are at stake.
There's no such thing as a perfect car. For every strong point in a
design, there almost always will be a weak one. You've just gotta learn
what your tolerance level is! BTW, speaking of tolerance levels, I've
gotta hand it to you for perseverance with that 2.8 GM engine! I never
knew anyone to go more than about 50k before they'd had it with that
thing! In fact, is is true GM sold a huge number of them to Jeep just to
get rid of them?
I enjoy this torqey American push-rod engine very much.
It is wonderful in the mountains where I live. No wonder Jeep
took the thing. Perseverance with it? Well, I owned a couple
of FIAT's, when I lived for many years in Eastern Europe, so
the 2.8L GM was really not a big deal, please believe me ))
