Car technician or Studim car technology or ???

Hey, there’s no topic where 100% of this fits in, hope that doesn’t bother anyone! I need a few tips / advice / experiences I’m a car master and still at the Bundeswehr, but the end soon and I have the opportunity to train… the question is now how and what… From the pure basic idea it would appeal to me to be a master in the customer area later (Kfz acceptance, customer service, KVA’s, invoices…..) Well, for that I fulfill the Vorr But I don’t want to let go of my training time and the money that is available to me.So what now… Studying? this opens up other possibilities for me of course…. is the most suitable vehicle technology (as Uni Osnabrück is near), what possibilities do I have with successful studies? Is a coming into the profession of a service master dami t lighter? am I too overqualified to do so? if so what other possibilities do I have? In Dortmund the technician is offered in the car trade… but will unfortunately be difficult due to the distance (110KM) … (woman, child….) What do you mean? That I have to decide myself is clear how above written tips ect…. Thank you
