I am amazed at your service costs and service (including a valet etc.) in the South...
Us lads in the North (in the sticks of darkest Cumbria) have limited choice in Dealers to go to.
Can I first say that I am generally very happy with my Xtrail, I like the style and driving position. However, my experience of Nissan Dealer Servicing is not good I'm afraid, Northern National Group Ben***ld Carlisle. Due to lack of competition, in Cumbria, my experience is that they seem to charge what they can get away with. I have looked through my service costs for the last six years, and the prices are not good reading, I do not think it represents a "fair" deal and Customer Care is lacking....
2006 M1 Service (11856 miles) £201.52,
2007 M2 Service (17946 miles) £220.96, (reduced Service works undertaken "due to low mileage")
2008 M3 Service + MOT (26165 miles) £313.02,
(reduced Service works undertaken "due to low mileage")
2008 bought Nissan Extended Warranty for a further two years for £459.00, to keep my repair costs down, or so I thought...
2009 M1 Service + MOT including replacing defective discs all round inc. pads (33546 miles) £815.43,
Not happy, and feeling I had wasted my £459, I took it up with the Carlisle Dealer, Nissan UK, "Nissan Extended Warranty" and the Financial Services Ombudsman, did not know about this Forum at that time, finally after a battle for almost a year I received cheque from "Nissan Extended Warranty" (in fact through "Car Care Plan" not a lot of people know that!!) in the sum of £501.93 in settlement
2010 local garage service + MOT and replacement of defective front discs [after only twelve months] and pads (39494 miles) £248.68 [Last year I had the car serviced at a "local garage" with its MOT, and felt that I paid a very reasonable prices.]
2011 13/07/2011 M3 Service, and repair to power steering fluid leak - with an alternative Nissan Dealer (formerly a Renault Dealership in Penrith with an "excellent service reputation") (47k miles costs to be confirmed)
So as my car is back to the alternative Dealer on Wednesday for an M3 Service, and power steering - we will see what the damage is this time.
Hope this is of use, sorry it is so long, best wishes, John
