If you wish to undertake auto repairs to your TGB 303R then it will always be a great idea to own a Workshop Manual for personal reference if perhaps you want to know simple methods to remove a particular component for example, the Dashboard and match it again perfectly.
TGB 303R Workshop Manuals offer you unique diagnostic guides on your automobile so if something is not working it will help you identify what the problem is and methods to repair it. Then you are able to analyse if this can be achieved on your own or if ever the job is just too big you can still book your 303R right into a decent mechanic.
