G80 question

I have the little traction control button below my radio, so does that mean that I have the G80 diff. or is it some cheaper traction control button/system?  Also, is there a way I can enter my VIN somewhere and see what was included with my car from the factory?

Look in your glove box for the SPID label.  All the options should be listed and G80 will be listed as G80

Ahh ok, thanks.

The G80 is a locking diff.  Traction control is electronic and uses throttle and brakes.
