Advice
This is a SALES position. Even though they advertise it as a management position, it is purely sales. You get a lot of experience with sales and if that is what you are looking for, than this is a great place for you to be.
When you first start the job, be ready to spend a lot of your day driving around and washing cars. Management has a large portion of their income dictated by how much their branch sells. It is likely that if you are not good at selling from the start, they will assign you to do more customer pick ups.
