I had my 197 serviced yesterday at kitchens of burnley cost £200 for a 2nd service and I also found out that the 3rd one cost £250 this includes new spark plugs. The staff there are really helpful and I would recommed them.
^^ Thanks for an update!
Im due a service in a few thousand miles and not looking forward to it. I normally put my car to a local garage (non Renault) but they only use genuine Renault parts and have a very good reputation, should my warranty be ok?
