If you wish to accomplish fixes to your MZ Charly then it is usually recommended to possess a Workshop Manual for a reference if perhaps you need to know methods to take off a certain part much like the Door and fit it again appropriately.
MZ Charly Workshop Manuals gives you precise diagnostic guides on your car or truck so if something is faulty it helps you work out what the problem is and ways to fix it. You will be able to evaluate if this can be achieved on your own or if the job is too big you are able to make a booking for your Charly into a local repair garage.
