You need to search around the site a little. There are several threads on production. First you should ask your dealer for a print out of your workbench order. This will give you the current status of your car and also your work order number etc....

The above thread has hundreds of pages, but if you go through it you should find some good information.
Here is the event code list that I originally copied from this site, but I've seen some others listed on here that have a LOT more codes listed.
1100 - Order placed at dealer
1101 - Order accepted by GM
2001 - Order generated to dealer
2005 - Order replaced with GM Prospec order
2050 - Order changed
2500 - Order sent to production - preferenced (dealer might have build date)
3000 - Order accepted by production control
3100 - Order available to sequence becoming more stable
3300 - Order selected for production by assembly plant
3400 - Order broadcasted for production
3800 - Vehicle produced (the vehicle most likely will be on it's way by now)
4150 - Vehicle invoiced to dealer
4200 - Vehicle shipped
5000 - Vehicle delivered to dealer
6000 - Vehicle delivered to customer
Hope this helps you a little. Just search around the site and you should find some good info.
Also, get the workbench order info from your dealer and then call every once in a while to get an update on it. Hopefully they will be cool and give you updates. Good luck.
