Great, thanks very much.  I work out towards Cambridge, which is handy; I'll give Marshall a try.  
Any idea how much the service 'should' be, just out of interest? 
  
So where do all the other people who are located around the E.Midlands take their Zeds for a Nissan service?  I don't live that many miles from Chesterfield and I know there are people here from there that own Zeds; where do you folks take yours? 
  
Cheers,
