So first of all, your profile is fine for a Business School. Plenty of people from the automotive industry go to business school at some point. As for which school: the best place to start is schools which will provide you what you need for your goals. So the first thing I would suggest if to define for yourself specific goals. The schools close to Michigan in the US are a good place to start. (Maybe Germany too, if you are willing to learn German!).
Then of course you would have to take your GMAT. I think that top schools might be a bit out of range for you given your profile, but that does not mean that there are not fantastic business schools for you out there.
Financial aid can be tough to come by, especially if your grades and GMAT are not stellar, and in most schools is awarded based on merit.
Hope this helps and if you have any further questions, do not hesitate!!!!!
