Yep, had that conversation earlier with my dad - used to be remarkable
if a car did 60k without three refurbed engines etc.

I'd say that unusual. 40-60k was more common before a re-bore, etc.
My father had a new 803cc Minor. That wore out its engine near enough at
the same time as the first set of tyres.

it down to better hose materials/design - and would replacements
incorporate these? Assuming they are new ones rather than NOS.

Might be affected by a better balanced engine stressing the hoses
less. Particularly hoses that go from the wobbly engine to parts fixed
to the bodywork (like a rad). Is the Beemer a straight 6?

15K for the cylinder head rebuild on my Grandparents Marina.

The "rubber" has changed somewhat in the last 30 years though, & the
reinforcing isn't made of cotton anymore.

I asked in my local factors, when I thought I'd do a precautionary change having
had one split in the past and he replied, ' Oh we don't get asked for those
anymore' whereas historically, they would have had them on the shelf.

And of course we never hear of modern cars developing hugely expensive
faults after modest mileages, do we?

Only very rarely.

I've known modern cars that have been run for 50K without ever having an
oil change.

Things like BMC A series engines would often need at least a valve gear
overhaul long before that time, and that would be with oil changes every
3,000 miles.

I can still remember reading with some incredulity the letters page of a
motoring magazine in the '60s of an owner claiming to have got an engine
to 100k. Now, one the *didn't* last that long would be more newsworthy.

Running unleaded on a 'leaded' head?
BY the time the Marina had arrived 100,000 miles on an engine wasn't
unusual.

Apart from the usual slight shimmy at idle a V-8 is pretty smooth.
Certainly more so than the average engine these days.

Would have been unbelievable on a 1.3 Marina!
