In my current quest to source a good car I am getting mixed messages about the required service periods.. I am being quoted by many that this car has had 'long life' services? and hence the 15k to 20k intervals. One garage suggested a car had 'full' history only for me to find out that one interval had gone over 38k? What is the required/recommended intervals guys? And whats this 'long life' service business? Thanks J.
