SteveT,
Yes you are right about moving the plugs every year or so. I've not had my car a year yet and I know from other issues that it's been polished more than it's been maintained.
These new iridium plugs are said to have a long life.
Peter,
Yes I was thinking about something on those lines. Not sure that I want to pay £200 though?
Cheers
John
