2004 Mazda 3s - 30k service in chicago

[kujorulez]

Hey all,
I have a 2004 Mazda 3s (I love it). It's at 39,000 miles, but I need to get the 30k mile service/maintenance. Should I go to a mazda dealership for this, or can I save money by going to another service shop? Also, if you do have any advice, does anyone know a good place to go in the Chicago-land area?

Thanks in advance!
