But to the original posters question, you don't want to just look for BS23J0B. There is currently an AAR for sale that has tags that have that but the VIN is out of range for an AAR so we know it is a fake. Only certain VINs fall within the excepted range for AARs. The range for 99% of them is between 274### and 309###. These also fall within the scheduled production date range of 3/11 and 4/17. So your car looks good.
