With most new Ford cars where you get a Ford warranty you have to get it serviced at an approved Ford dealers or you can have problems if something goes wrong.Would you take a chance on invalidating your warranty on an expensive Focus RS for instance by servicing it at home yourself just so you can say you are a hands on enthusiast?
With us owners of the older Fords its different, a lot of people will do work themselves if they can but even then there are some jobs that are best left to a specialist.
To have the facilities and skill to be able to do every single thing yourself on your car is not very likely but you are still a true Ford enthusiast in my opinion if you pay an expert to do some things which you cant tackle yourself.
When I go to a Ford car show and look at a well sorted new or old school car the question of who did the work on it to make it so good never crosses my mind, I am just admiring it for what it is.
