jjy59, your OP is entirely correct. In an attempt to further confuse buyers, GM, at various places, calls the codes for the items you listed - RPO, or "Free Flow RPO Codes". They are all LPO dealer installed options and those codes are all actually LPO. I think most of us picked up on that, but I can certainly understand why bolteon593 called you on it. You were talking about LPO options, but appeared to list RPO codes!?! And then there's guide number, allocation, concensus......
