This is a request for anyone that will be seeing the production cars at any of the North American auto shows this year. See if you can get close enough to record the VIN off the display cars. After members here start to buy them it will be interesting to compare the number of those cars (car show) to those cars that have been bought by forum members. Does GM still use plant, engine, tranny, diff., and color numbers to make up the VIN? If not, what is used today?
