Well - just as we often repeat - they are great cars - but unfortunately the opening post is exactly what every owner said right up to the day before their engine went wrong.
I am genuinely very pleased to hear so many run OK for long periods of time - but if we had statistics that revealed - say - that 5 % fail after 16 years, another 8 % after say 20 years etc - it would still leave the vast majority repeating your opening line - and good on them.
However this does not mean the other % also never go wrong and the older they gate the more expensive they become to repair as well.
Good luck with yours and I hope you can repeat your slogan throughout your ownership - if not - you have access to a great repair facility from us.
