Just had a partial 4 year 42000 mile service carried out by Jaguar Specialist Andrew Wilson Motors, Dinas Powys, Cardiff who from personal use over a number of years, I would be happy to recommend. I cherry picked what I wanted them to do from the Jaguar Service Schedule which comprised of oil and engine filter change (supplied), check and report on brakes. They also carried out an MOT and changed 2 tyres (supplied). Total cost was £194.00. I have bought a service book which they stamped for the work done. The rest of the items detailed on the schedule, I did myself and all these can easily be done by anyone with a basic knowledge of the workings of a car.
Manufacturers and dealers would have you believe that only the dealer can correctly carry out a service. The real truth is that unless you have any problems with a car, fault lights on etc, which can only be investigated using correct applicable software, with a 4 year old car which you intend to keep, you are wasting lots of money going to a main dealer as opposed to any other competent garage that you trust. The only dubious advantage being that you get the services listed online. If and when I come to sell my car, I will be able to produce a full history backed up with garage stamps and receipts which for me has always had a positive influence on my decisions when buying secondhand cars.
The value of diesels has dropped like a stone anyway. I know others will disagree, but in my view, the amount I will have saved by not using main dealer service will more than compensate for any possible loss of added value this might bring.
Out of interest, I dissected the official service schedule into 4 parts as shown below:
MOT, SERVICE, DRIVER, DRIVER +
MOT items are covered anyway so no need for them to be done twice. 21% of the list.
Service items by garage for those who do not want to open the bonnet or the boot. 49% of the list.
Driver items are what I would consider the user would be totally familiar with anyway. No need to open the bonnet or the boot. 33% of the list.
Driver + items would be for those who like a bit of motor diy. In this case that would be 64% of the list with Service items then dropping to 18%.
