If you choose to perform repairs on your own Beta Minitrial then it is always a good plan to own a Workshop Manual for a reference in case that you need to know easy methods to remove a specific part for example the Door and match it again in the correct way.
Beta Minitrial Workshop Manuals provide you with exact diagnostic guidelines for the vehicle therefore if something is not working it can help you find out what the issue is and easy methods to repair it. After that you can analyse if this can be done by yourself or if ever the job is simply too big you can make a reservation for your Minitrial right into a trusted car garage.
