Good luck.

The odds and difficulties of getting an automotive engineering job for a major auto manufacturer is almost equivalent to a good HS football player becoming a multi-million dollar NFL football player.

Its not impossible, but you will have to work really hard to achieve your goal. Try to start with some grunt work in the automotive customization field since that kind of experience will prove much more helpful than just working in some dealership's service department.

Also, when you get into USF (of maybe even before) check to see if they have an SAE chapter. The people in that group can provide you with a lot of good information about achieving your goal.
