I did a quick google search for "GM Doraville", and came up with this article:
http://www.georgiaquickstart.org/qui...News17/gm.html
I would suggest calling up the plant and asking to speak to the people listed in this article. Also, mention the article - not only will it show that you did some research, but everyone loves flattery.
Also, for some help in getting through phone trees and secretaries, follow this link at CollegeGrad:
http://www.collegegrad.com/jobsearch/12-0.shtml. Though the site is for job hunters, the same tactics can be used to get in touch with key people within the plant. Good luck!
