What would be the purpose of having a 1LT and a 2LT if you put all the 2LT options on the 1LT? The 1LT is a lesser optioned choice at a lesser price. I don't know what else to say in response to your statement......
As far as the squeak, take it back to the dealer and have them fix it. Keep bringing it back until your satisfied that the sqeak has been fixed. Maybe you should have bought the 2LT???
