Lem LX 1 Workshop Manuals can provide identifiable diagnostic details with regards to your vehicle so if something is playing up it helps you determine what the situation is and some ways to repair it. Then you are able to evaluate if this can be done on your own or in the event the job is simply too big you could make a reservation for your LX 1 in with a decent mechanic.
