Shocking stuff id say your right original plugs from day one serious penny pinching , ,although I know of a toyota auris bought new in 2007 still on its original oil its never had a service in the last 7 years

When it comes sale time the garage will have it advertised as one lady owner "mint condition"

Haha, I know they are longlife plugs but that's taking the piss!

@[Gar] that's incredible, I love to service it...

I think the E92 320i I brought in to you @[Valdelisbmw] had the original plugs before you changed them?

That car had been main dealer serviced from day 1, under warranty until a few months back.
They also didn't spot the timing chain needed doing...prob cos the computer didn't say so.

Plugs not due on the newer engines until 100000kms, bit of a joke yes but that's what they say!

[Valdelisbmw]

yes ,and even on E60 models not much less recommended for plug replacement .In think it should be BMW guarantee if they didnt last 100k km :hehe!:
btw ceramic part missing from plug went in to the engine,and im sure they didnt last even half of recommended mileage
