I often get calls from so-called specialist workshops asking for basic technical information that is in the workshop manual. They claim that they work on and look after XKs but don’t have a manual. I really do find this quite unbelievable. Guy Broad Parts are experts and we refer to them all the time for detailed information that we require. A manual is important to have if you only do the odd job on the car yourself. It just gives you that extra little bit of knowledge about your car.
