Can anyone give me more info on these options.
1AY ORDER MODIFICATION STOCK
1SA OPTION PACKAGE 01

Thanks

 

not sure about the first one, but 1SA is just a dealer order package... when the dealer orders a car that "package" is basically a preset list of optional equipment. Every car has at least 1 of the "option package" RPO's. That preset list is furter defined witht he rest of the RPO's.
