When information is needed in the more technical areas,this manual says to take the car in to a professional for the repair. Now why would a person need a repair manual put together by someone that feels the person reading it isn't able to preform the task at hand?I surely do not need a manual to tell me I need to "take" my car to a professional for repairs.If I wanted to pay someone to repair my car I sure as heck wouldn't buy a how to repair manual that states it covers all areas of repair.This manual leaves a lot of questions unanswered in the repair of the Miata. Over all IMO... it is a very poor manual that gives the feeling the writers really didn't have much experience in repairs of this model vehicle.
