It's one of the biggest in the country. Being in the Motor City and all.
The big three will reveal a lot of new models, concepts, etc. at this show since it's home turf. Cobo is huge, and it's filled with shiny new cars. If you can buy it in the U.S., it'll be there, basically. Plus a lot of stuff you can only look at. A lot of companies have an owners lounge, like "show your keys" and get in, and so do the big three for employees. So if you have a relative with a beamer or something, borrow their spare set of keys.
